Hi, I'm new here and so no judging!

I've always had a fear of, well, everything. I'm scared of men, open rooms, lifts, people, speaking, etc. But right now, it's getting to the point where I am scared to go outside, and it's not like there is a valid reason as to why I'm scared.. I just am.

Today for example, I went into town to buy some things for Valentine's Day. I get into town and end up freaking out. My heart started beating really quickly and I started getting warm and shaky. All I could think about was everyone else looking at me and judging me and being all nosey and judging.
I hid in the bathrooms in one of the shops and cried for 10 minutes before getting the courage to get out, and I ended up going home after being in town for just 30 minutes. Since town is about 5 minutes away on the bus, after an hour of being home, I calmed down, had something to eat and went back into town. I had some games I was going to trade in to the game store, and decided to go there first because I knew what I was doing (I'd traded plenty of games in there, and bought them and the staff know me).

That failed because I forgot my ID. I panicked again and went home.. again. Now I'm sat in my room crying, I texted my boyfriend who knows how silly I can be sometimes and he's going to come into town with me tomorrow. He's one of the only people (besides my mum) who can take me places and keep me from panicking over nothing.

But anyway, I feel so dependant on him and feel sorry for him if I'm being honest. When I'm not with him, I stress out, panic and just get down so much more easily compared to when I am with him. My worst fear is being too clingy or overly-dependant, so I don't know what to do!

I had a psych-assessment last week, but the psychiatrist said I was fine and just being a teenager (I'm 16, almost 17). But she barley heard me out and I think she might have been wrong. Surely every teenager in the world, doesn't get scared when out in town for no reason at all. I hardly even got to tell her about me panicking or worrying so much, and instead she simply asked about my sleep, appetite and if I had any friends. She took a family history, and asked how my boyfriend and I were getting on, and that was about it.

So basically, what is wrong with me? I'm not looking for some diagnosis, but I need some advice on how to cope and gain some independence back..

Oh my, sorry it's so long.. I understand those who don't read it but it would be very useful and appreciated if you could read at least some and offer your advice.

Thank you!
