anxiety ?

I have really bad anxiety. I know that for a fact, and I'm scared... I am scared to do anything and everything.. I can't go to the store, I'm scared to bumb into someone I know, I even get frightened to talk to the cashier....when i do go to the store I never go alone,my husband goes with me and if he leaves me for just a few seconds I get so nervous and want to freak out! my heart drops Everytime I get a phone call. and I am scared to make this post . I feel so alone and I just want to know is anyone else like me ? I never was like this growing up it started when I was 15, and it was small things at 1st, for example when people would come to our house I would stay locked in my room, I stopped going to family gatherings... small things like that. I need help but just the thought of going to the doctor freeks me out ! I went when I was about 20 so 2 years ago and my Dr kind of ignored the situation... have so much more to say but I'll just leave this here .. it's not like anyone will read it or reply... I'm stuck
