Where do i go with my life?

I'm going to make a long story short, but the past year, i've dealt with really bad anxiety from thinking i'm deathly allergic to every kind of food, happened when i developed an allergic reaction to Ibuprofen. The anxiety to that takes everything away in life. Back in January, i went on from going to a community college, to a University. And my anxiety got worse, i didn't know what to do during that time, that allergy fear was worse to, i stopped eating and my grades really suffered, to the point, i was literally failing every class. Life was eating me on the inside, i though about suicide, but i didnt. In March, I've decided to take things into my own hand, I exercised, i said FU to my anxiety, even if it was there. and i felt better, i went from a 0.0 GPA *LITERALLY!* to a 2.13 GPA. and i was proud of myself! But even then, when school ended in May, my life still feels empty, i don't have many, if any at all, friends to hang out with and i have a hard time making new friends, i don't want to eat out either, that fear is still in my mind, but i've been eating a lot more too. I just don't know where to go with my life, i still feel empty even though i know i've improved since March, I feel like I was walking through a long dark hallway, and i finally found the door! But it's locked... how do i open it? I just don't know what to do, i still feel anxious from time to time, but it's better. Sorry it's long, i hope i can get an answer.
