Seroquel and body dismorphic disorder

Im from Cork,Ireland.I was put on Seroquel to treat my Body Dismorphic Disorder.I have really disliked the way i look for years.Hated the way i look in fact.I was very badly bullied all through my school life and teenage years because i was very heavy at that time.Needless to say i ended up hating myself with a passion.When i left school i went on mission to lose the weight and i lost about 6 stone by eating healthy and fast walking.I can't tell you how proud i felt and iv never felt proud of myself in my life.Then the effects of my teenage years started to creep up on me.I needed to face them.That was a very,very painful time and to make a long story short i got severly depressed and BDD set in.And guess what?I was put on a drug that put the 6 stone back on again and even more.Even though the Doctor's have noticed this they have continued to keep me on this drug.Every time i bring up the issue with my doctor's there response is 'Oh you need to watch the diet'.Now I tell you, I DO NOT eat alot nor do i eat rubbish.And this drug is ment to make me feel better.Now how stupid is that.
