Feeling stressed out...

At the moment I am in a positive place with my treatment. I'm doing fine. So now my attention is directed to everything else that isn't fine. I feel like I have the whole world on my shoulders. I am stressing about my mum, as she is constantly in pain and the doctors aren't sure why. I get stressed out when my parents argue. I get stressed about the future. I get stressed out about the things I can't control.
 Some of you may know that ever since I have been in cancer treatment, I have become a bit of a control freak, so things that I can't control really worry me: My mum's illness, relapse, being passenger in a car, etc.
I guess it is all just taking its toll on me, I woke up this morning from a terrible nightmare that my mum's pain was caused by a cancerous tumour. It really upset me, and my mum being in pain is scary as I constantly think of worst case scenarios, because the worst case scenario happened to me.
I am stressing because I want everything to be fine, but I need to learn that not everything can be fine all the time.
For now, I am just going to try and not let everything get to me, and start focusing a bit more on me. I will still worry and stress, but I hope I can work my way through it, like I did with my anxiety. Hopefully I can see my therapist soon, so she can help me through it.

Thank you everyone for reading this post, I really just wanted to get my feelings out to you guys. Hopefully soon I can say I conquered stress, like I did with my anxiety, and help any of you guys who are dealing with stress too.
