I'm taking 80 mg of fluoxetine from past two weeks still I did not feel any improvement what my problem is i'm scared and anxious if people did not respond to my msgs or calls, until they reply or respond my mind still thinks about that, after they answered again mind switches to another same thing. It's really killing myself. I can not control it. Especially if someone block or dint response im going very anxious and I keep on trying to contact them until they reply. If its closed ones means there is a logic in asking them but for me its happening with online friends, just known friends. What is the problem with me. I feel like lost my mind. I can not concentrate on anything.
