You are not broken. I think just about everyone here has an illness they continue to work on. If you were born diabetic would you blame yourself? It's not your fault if you have social anxiety. Part of mentall illness is contributed to genetics. I was very shy and basically an outcast in high school. When I got to college I was very shy for the first two or three years. What really helped me was taking a public speaking course. And I changed! I got my teaching license and taught high school for two years. I would never ever imagine that I could of done something like that. Will your social anxiety ever completely go away? Maybe not but it can get better. Sometimes I still get nervous talking but other times I'm fine. I know teachers who's biggest fear was talking in front of students. I would have never thought one of my teachers could of been afraid of talking in front of kids but it can happen. I'm a big believer in therapy if there is anyway you can get it. If your an adult and your not working (as it sounds like you are) I think you might be eligible for Medicaid which pays for almost all medical stuff including therapy. You can apply for it online. In the mean time set small goals for yourself. So next time you're in class make it your job to speak to someone about the weather for 2 minutes. That's it just 2 minutes then you can be quiet the rest of the time. Slowly increase the time and change the subject, like talk about new movies. You will realize you can do it, it's hard work but change is always possible.
