How cancer can make you feel
There are things you can try to help yourself feel better, even if you feel low and as though you can't do anything. You may think nothing will help, but you won't know until you give it a go. You may feel you have no motivation, but often doing things can create motivation.
Notice if you have any guilt about these thoughts. Try to let them go and not judge yourself for having them. Holding on to them and being hard on yourself will not motivate you. Instead, focus on the efforts you are making and try to develop a compassionate understanding. Think of what you might say to a loved one if they were in your place.
At first, you may find it very difficult to want to try any of these suggestions. But along with other treatments from your doctor or specialist nurse, they are worth trying when you feel ready. They can become a new habit.
We all have sleepless nights and know how tired, cranky, and dazed they can make you feel.
If feeling sad or depressed makes you have trouble sleeping at night, it may help to change a few things about when and where you sleep. If you have severe depression, sometimes getting a lot of sleep may not help much, and can make you feel worse.
Do let your doctor or specialist nurse know if you often have trouble sleeping. The tips below will help you to address your 'sleep hygiene'.
Go to bed and get up at the same time each day.
Do some light exercise each day to help tire yourself out.
Try to cut down on napping a lot during the day - you may find you then sleep longer and deeper at night.
Avoid caffeine (coffee, tea, chocolate and cola drinks) after early afternoon.
Have a light snack before bed to prevent hunger from waking you.
Spend time relaxing before you go to bed - have a bath, read, listen to music, use a relaxation app or podcast.
Try to sleep in a quiet, calm room that’s not too hot or cold. And remember, an untidy room may be distracting and make you feel anxious.
Avoid drinking too much alcohol before bed - you may fall asleep to start with, but you'll have a disturbed night.
When you really can't sleep, get up and watch TV, read, or listen to music until you feel sleepy. Or try simple, relaxing things like taking a warm bath and having a warm, milky drink. Then go back to bed and try again.
Some symptoms might make you feel more sad or depressed than usual. It is very important to let your doctor know about your physical symptoms. There are many treatments that could help. The better you feel physically, the more help it will be in coping with your feelings or with depression.

After cancer treatment, it can take a long time to develop an understanding of the way you feel about it. You are having to process the reality of having cancer as well as coping with the side effects of the treatment. Some of these may be life changing, for example, getting used to changes in how your body looks and functions.
While cancer treatment can make you feel ill, some people do manage to hold on to some of their routines and habits during their treatment. You might need to take time out of your normal routine for treatment. It is important to allow yourself enough time to recover after treatment.
It is also very important to manage your expectations of yourself. Be kind towards yourself and adjust them if you do not meet them. These may be temporary changes, and accommodating them can help you recover from them faster.
At first, you might feel a sense of loss and miss your contact with your doctors and nurses. It can be useful to talk to someone close to you.
It is difficult to predict in advance how much recovery time you will need. You might feel very tired for some time after treatment.
People around you can forget that you have been through a very physically and emotionally demanding experience if you look as though you are well. They may expect you to do things which you do not feel up to or have the capacity for. So it is important that you just do as much as you feel like doing and try to get plenty of rest.
Don't feel that you are a failure if you haven't been able to manage on your own. Once other people understand how you are feeling they can be more helpful to you.
You might find it very hard to come to terms with the thought that the cancer could come back.
Even if your cancer has been cured by your treatment, your doctor may not be able to be sure about that for some years.
You may never be told you are cured.
Everyone copes with this in a different way. Some people can put it behind them more easily than others. Others would find themselves thinking about it again and again. If you find this very difficult, it may help to have some counselling, even years after your treatment, to live with this uncertainty. Your counsellor can help you to explore your feelings and find a way to cope with them.

Being positive and thinking positively can help you cope with cancer, but it is natural to also feel upset and frightened sometimes.
After a diagnosis of cancer, you might have a range of feelings including fear, sadness, anxiety and depression. These are normal responses to a stressful life experience.
Counselling can help you come to terms with your cancer. Understanding what it is and how it can help, can help you decide if it is right for you.
There are a few ways to go about finding a counsellor.
Whether you are someone with cancer or a carer for someone with cancer, we want you to know that it is common to struggle with your mental health when dealing with a cancer diagnosis. But there are people who can support you during this time and things you can do to help yourself.
