I certainly would see an OBGYN for the 'period' thing.Hormones are... at instances... a huge contributing factor to mood.I have been hospitalized for self injury...(always turns out to be p.m.s)....I also get paranoid,for me,this is due to the fact that I have experienced situations of abuse,betrayl,ect.....and I never saw these situations coming.So obviously,since I was surprised by these things...I did not trust my perceptions and had to be 'prepared' and on edge about all the 'possible' things that 'could' occur.So as you can see ....our experiences can shape our interpretation of things around us.I feel you could benefit from a supportive T who could explore these things with you.You aren't different....you just have things to explore.(((safe hugs)))~WOolf
