Hello to everyone, i am new here, i have a problem and would like to solve it somehow.. sorry for my mistakes in english language.

I will try to describe you my problem and maybe you will have something helpful to say about it. So basically i think im suffering from some kind of agoraphobia/emetophobia or some similar social phobia. I had that problem since i was a kid, mostly in elementary school. I would vomit in some situations that would be stressful to me, and was anxious about going to school etc. The problem was mostly gone when i was in highschool, in my teenage years. Then, i would only be anxious in rare situations that are stressful for most people. Also, after highschool i worked and lived normally, the work was "with people" and i was always relaxed, confident, and had no real problems, i was much or less a happy person. So the thing is, the problem is back. It came back about 2 years ago (im 24). I started to be really anxious about "normal things", like going out with my friends, going to market or whatever. Basically every time i have to go out of my house, that is stressful to me, and i feel anxious, get panic attacks, like im scared and have a feeling like im choking and have a need to vomit, but am also scared of vomiting in front of other people. So in those two years back i stopped working, i stopped going on my colleague classes, my socialising with friends is on minimum, i rarely go out of my house. All that is a big problem for me because few years ago i was confident, i was working, i had some money, i was training in gym so i was in a good shape, i was outgoing, all was pretty much fine, and now i feel like some helpless child, its really bad, like my life stopped and im just waiting to die I'm aware that this phobia or whatever it is, is irrational. I know its stupid to be afraid of going outside, but its like my body doesnt know this, and reacts opposite. I told some of my best friends about this problem, but didnt told it to my family because im kinda ashamed of that (i know, health problems are nothing to be ashamed of and i should talk to them, but i am ashamed and feel stupid about it). I dont know why this problem got back, i dont know why is it here, but its ruining my life and its really really bad, and i dont know what to do, i feel like i will never be like i was before and that is killing me.
Please help.
