seriously, i don't know what to blame my behavior on lately!

i am having mirena removed tomorrow so i am anxious to see how my depression/anxiety/eating habits change. i have gained over 20 lbs since mirena went in last summer but over the past 2 months, i can't seem to get the food shoveled in my mouth fast enough! my "pms" comes about every 2 weeks? maybe it's the sadd thing? (seasonal depression). i already am taking zoloft and wellbutrin. i can't imagine taking something else! i can have my own pharmacy at home! LOL!
so i guess what i am asking is if anyone else has this kind of depression/anxiety/eating habits on birth control? to the point that you feel totally out of control!
