Health & Social anxiety

Does anyone else suffer from social anxiety and health anxiety? I'm too scared to take medication for it because I'm scared of the side effects but I'm starting to feel like I probably need a really low dose of something. It's preventing me from going in stores, going to the drs, getting a job, etc. I get these intrusive thoughts that something bad will happen to me, like I'll faint or have a seizure or something insane. That's never happened to me before but for some reason I'm scared of it happening. The only health conditions I have is BPPV (vertigo) and anxiety. When I get the vertigo attacks it causes panic attacks and then it gets worse from there. I'm getting a support cat Friday from the animal shelter, which I hope will help. Every time I go out to the store it feels like the walls are closing in, the lights overstimulate my eyes, and my chest feels tight and I get really shaky. I was never like this, when I was a teen I could be at Walmart for 3 hours shopping, same with the Mac, target whatever. Now at 22 I loathe going to the store. It's easy for me to say I can avoid it but I have 2 toddlers that will soon want me to go out and do things with them. I'm really trying but being around so many people sketch me out so bad. Around thanksgiving I went to a restaurant for the first time since last summer and I actually did good but when we got into Tj max and home goods I started panicking. It really sucks being like this. I've had job interviews and I've practically failed at them all.
