Attitude problems

Hello, i need an advice, suggestions, a resolution but I need help

I currently have a 2 year old from a previous relationship broke up with BD when my 2 Year old was 10 months

Fast forward to a year later I started dating this amazing man we been together for 5 months already but things are starting to get a little rocky because of my ATTITUDE. Im currently on Twirla.

At the beginning I was very nice to this man I loved how well he has treated me since day one but im not sure whats going with me that i cant seem to control my attitude he already warned me that if I dont change my attitude he will be ending things which I dont want that because this man is amazing, good husband, provider and love my baby like if she was his own. But i do need help i have always had an attitude and im not sure why. ive been to therapy before but no improvements not sure if i need anger managements classes or what. Not sure what triggers my attitude, ive gained a lot of weight not sure if my hormones have something to do with this but I need help/advise or see if anyone has gone thru the same thing as me. I really want to change but i cant control myself when hes away at work i be missing him but when we are together we can be good for most part of the day but i would randomly get in a bad mood and starts giving him attitude.
