Without interviewing you in person, it is difficult to know precisely what may be wrong. There are two main possibilities. The first is that you have social anxiety. The second possibility is that you have schizotypal personality disorder. Individuals with schizotypal personality disorder characteristically have a great deal of social anxiety, tend to be loners, misinterpret situations, experience paranoia and have paranormal or peculiar beliefs.
A complicating factor in your situation is that you have been displaced from your home. Not being able to live in your home may be contributing to your anxiety problems.
You also mentioned that you have a history of abuse. That further complicates the situation and it may also be contributing to your current psychological symptoms. You blamed yourself but it is important to know that you are not to blame. The adults are to blame; you were an innocent victim.
In your letter, you stated that you have been prescribed medication. That means that you have likely been evaluated by either a mental health or medical professional. I would encourage you to speak to that person about the symptoms you have described in your letter.
The fact that you’re taking a medication that is not working is also important information that the prescribing physician needs to know. Ideally, you should be evaluated by a mental health professional and referred to a psychiatrist for psychiatric medication, if necessary. My main suggestion is that you need to contact the proper mental health professionals so they can properly assist you with your psychological problems. Please take care.
