Any advice

This has been going on for about 3 months now. I haven’t been feeling good.

It started with me getting somewhat lightheaded and shaky out of no where almost everyday. It would scare me. I started having panic attacks. I went to a couple doctors and med express. They checked some things and said I looked good.

I’ve been having pains in different parts of my body. Like today at work I had pains in my chest on the left side and was scared I was having a heart attack. The pain went away tho.

I have very low energy. Panic attacks from being scared of something being wrong with me. I feel tired.

At the beginning of January I went to a doctor that wanted to get my blood drawn, but I started to feel better so I never went to get it done but now I’m starting to feel bad again.

Idk if I’m just scaring myself or something is really wrong. Any advice ??
