Okay, here we go:

I've always been anxious. I didn't even know I was anxious until a few years ago, when a friend who was diagnosed with GAD said I was worse than him. Whoops.

I could give you lifetime of examples, but I think a couple of the strongest are that when I was a child, if my mom was late home from work, my sister would tell me she was dead and I'd be a hysterical crying mess. 
In my teenage years, I struggled with White-coat syndrome, and would tank test scores because of my anxiety. As such was always disinterested and bored in school.
In my adult life, every time I try to be sexually intimate with a women, my equipment doesn't work. This has lead to a downward spiral and self-fulfilling prophecy I haven't been able to work around.
My marriage is failing due to my constant needs for re-assurance and my work is suffering because as I work in a high stress environment where I need to think fast and I'm often bogged down in choice paralasys, I often second guess myself and basically think I'm an impostor here. 
I have another lengthy post about my issues, if anyones interested. 

I've been to therapists and they just... don't seem to offer much, they just listen then sort of don't really know what to say? I've been offered medication, but I've heard some real horror stories about side-effects. 

I just wish I knew what was wrong with me. Why don't I want anything? Who doesn't want anything? I just want to lie on the floor and not get up (nothing suicidal, literally just lie on the floor).

Any insight is appreciated.
