Hey guys. I'm not sure why I'm posting or what I expect to actually happen but I'm at the end of my rope. For background, I have a brain injury that (among other things) causes me to have extreme anxiety at times.

For the last two weeks, all I have thought about is suddenly dying. My cat died. My fiance's grandmother just passed away a few days ago. All I can think about is when I'm going to suddenly die moments from now. 

I'm not the healthiest person. Im 28 years old, 5'7", and about 200lbs now. Gained a little weight during quarantine. My medication normally keeps my anxiety in check. I haven't had a full on panic attack in at least a year. Until yesterday, that is. I thought my heart was going to explode and I'm still feeling the effects today. 

What can I do to get some relief from these thoughts ? I am scaring myself into a health crisis even as I type these words. Every little pain or discomfort turns into a terminal illness. I'm so exhausted after these last couple weeks (and last night) I can't focus on anything. The only thing I can process is I'm going to die soon suddenly. I just want to feel better and not worry about that. 

I'm sorry for grammar and stuff. Its not on the top of my priority list right now. I just want to fix this and I'm at an absolute loss for how to proceed. 

Thank you
