Is it normal i am becoming a sociol cripple?

I am becoming a social cripple. By this I mean my social interaction skills are deteriorating. I tend to get treated horribly when I try to express myself. Which has been a consistent trend since childhood. Why often as a child I would write.

In my older years I just kind of read and communicate stuff Via text/Social forums. Yet my social interaction skills are becoming worse. When I do express myself I am threatened with violence or am abused, mocked and humiliated for expressing myself. So every-time I try something just tells me not to do anything.

Though this is a two edge sword since when I cant express myself it often makes people think I am stupid or plotting to kill them(Something along those lines). So what should I do? I not one of those people who simply shuts it off and on. I am the same with business and with family. My job has not complained as long as I do my job.

After awhile you forget how to react to things and so you often have to fake behavior to mass your feelings. Since people wont understand what you are feeling any other way. How do I deal with this issue?
