Charlee,
So sorry to hear that you are struggling right now. Those inital few weeks after diagnosis are like a roller coaster ride of emotions.
Relief that you have a diagnosis, fear of the disease, relief that you are on drugs that are going to 'control' it, fear when they don't and you have to move onto something else. It's a really quite bizzare time.
Any drugs taken can intefere with your emotions (some more than others) and I think it is important to let your medical team know if things are closing in on you.
Acceptance is such a large part of having any illness once you can do that you can deal with it head on
Wish you well
