I've always been told I'm abit moody.lol!! For the past year or 2 they have got worse,days where I don't wanna get up or go out then others where im full beans and unstoppable. My temper is erratic don't care one minute then could rip your head off the next.My sex drive has always been average but lately I'm even scareing myself, I've been with my partner for 18yrs and adore him but have joined dating sites whilst agreeing to meet for sex. I can't even explain why,my behaviour is effecting my relationship to the point of splitting. Can someone plz help. My doc has recently diagnosed me with postnatal depression and I had a daughter a year ago, but feel it is more than this.
