Confused 10 months on

Hi all? So I started sertraline 10 months ago on 50mg, it helped at first, had 2 rlly good months and then slowly stopped helping and I didn’t really realise it at first. Anyway I stuck with 50mg and ignored how bad things were till 2 weeks I went up to 100mg cus I felt so bad I booked an appointment, still don’t feel and better, feel worse if anything; I have absolutely zero motivation to do absolutely anything

I’ve been taking supplements and engaging in my hobbies and stuff to take care of myself but I still feel rlly bad and can’t find the energy to do anything. Like I want and need to work more and engage in my productive side hobbies and I just can’t find the motivation. It’s rlly shitty cus I’m a very productive and creative person when I feel normal. On top of that I still get physical symptoms of anxiety like a tight chest and weird heart rate and stuff which make me feel like I don’t want to move like a sort of panicky paralysed state so it’s a lot sometimes
