TW: mentions of death and anaphylaxis

I've been on my fair share of medications over the past (nearly) decade. Some have helped, most have not, but never have I ever had a (mental health related) medication cause an allergic reaction, yet over this past year I've become immensely wary of nearly all pills. I was forced off Prozac in the winter and haven't been on anything since until now, but now I can't make myself take them. I have this overwhelming fear of collapsing dead like my uncle after I take em, I'm afraid of being alone and dying due to sudden anaphylaxis.

I hate being like this and know that I should take them, but I can't help but freeze up. Every single time, I get a mental image of my corpse, slumped over, on the ground. Every single time, it stops me. It sucks. I'm always fixated on the chances of bad shit happening; I can't help but to think, if it could happen to anyone, what's stopping it from happening to me? I'm hoping I can get over this bc if Lexapro can help me get rid of these god awful thoughts, I'll welcome it with open arms.

I know it's a silly fear, but I can't seem to shake it. I seemingly can't stop my subconscious from clinging to it.
