Trapped

Today I felt trapped inside my mental status. It is difficult to do something and not thinking about your illness. Everything you do, feel or think is linked to your depression.
But isn't it normal to be angry sometimes or feeling tired or having not so much fun. Isn't it normal that you are doing things that makes you not happy.
At the moment everything you feel etc. is linked to your mental health and all the time you are trying analyse all that you do, feel or think.
I have to stop with that because it makes my so tired and keeps me away from thinks that are really important.
I must focus on real life and not analyse everything.
