I worry about my cancer alot i'm seeing a therapist soon but what can i do now and aslo does cancer usually make you feel very sick and not a symptomatic?

It really depends on what type of cancer you have and what stage of cancer you have. This will determine how sick you will feel based on the symptoms you are having. Your oncologist can give you a better idea of this and how sick you will feel with whatever treatment you will need. Seeing a therapist is a good idea to help you cope with the cancer and its treatment. Best of luck to you!
