I need help, i want to talk to someone?

Honestly, i'm pretty lonely right now, maybe i can feel better if i post my problem on here to see if someone can help.

It's been almost 3 years since i've suffered from my first panic attack and ever since my life has been devastating, i had friends. Had. But because of it, i've had trouble going out and stuff. I was a hypochondriac, it was hard to live with.

Last summer, life has started looking up, i felt great but one day i took a pain killer and i had a small swollen lump on my lip, i figured it was nothing, but i decided to Google what has occured, it was probably the biggest mistake of my life.. When i read about "anaphylaxis" my panic attacks returned, and life felt terrible for a few days. But i got over it for a bit, i knew not to take an Ibuprofen. So i took another Ibuprofen related product and the exact same thing happened and i started to panic for a few days as well.

A few weeks go by and that was still on my mind to the point where i thought food can do the exact same thing, eventually i stopped eating a lot, i cut my diet, stopped eating Peanuts, Dairy, pretty much anything that can trigger anaphylaxis. I rarely eat, my parents are like "come try this!" i'm always saying "no thanks" even if i've eaten it before. Lately, i've developed skin rashes and the first thing that comes to mind is allergic reactions.

I'm limited on what i can right, but i can't eat a lot, i want to eat, but i just can't, what should i do. Someone has to help.

I'm 20 years old.
