I'm old enough to be your grandmother, but have had a lifetime of obsessive thinking. Counseling may help you...I have to admit, though it did help me in realizing my behavior patterns, it didn't help me with the obsessive thinking. I think it's a brain chemistry disorder. I say that because once I was diagnosed with depression, I was prescribed an antidepressant. It was my family physician, not a psychiatrist, who made the depression diagnosis and prescribed the medication. I was in my early 40's when this happened with the doctor. It was a life-saver for me. Had I had the benefit of medication earlier in my life, I'm sure it would have saved me a lot of anxiety and obsessing. I DO still find myself occasionally thinking obsessively, but I'm able to control it and stop it!

Have you considered seeking a diagnosis which would result in a medication? I recommend it.

Also, I'm very sorry, and truly shocked!, that your "friends" would call you such cruel names. That's totally unacceptable. Being shy and quiet is fine (I'm an introvert myself!), and I find one should limit friends and acquaintances to those you truly trust and with whom you feel a connection. You WILL find them!

Are you in school at this time? I have a lot of encouragement about school.
