Lamictal and nuvaring

I have been on Lamictal for about 3 and a half yrs now for Bipolar 1. Overall, I have had a really great experience with the drug. I started with 100mg and then went to 200mg after a year and a half. Now I take 225mg as of a month ago. For about a year and a half I had the acne on my chin and then it went away suddenly (thought it was cutting out dairy from my diet though). I have been extremely fatigued for awhile now. 7hrs of sleep is not good enough for me so I end up taking long naps when I have the opportunity each day- I always want to sleep. I feel stupid and lack focus and motivation. I use to be a social butterfly and now I feel so exhausted when entertaining. I am a personal trainer and am in the business of making others feel better, but I seem to be feeling worse. I have experienced weight gain as well and that is hard for me since I use to be bulimic and have always had poor body image issues. I was on the NuvaRing for 5 months and it made me sooooo depressed so I finally got off that and feel better- don't mix those 2 drugs.
I am going to ask my doctor to take me off of it this week because I am ready to trust God with my mental health. I have a great support system to help me through the tough times and if I want to get pregnant, I have to go off it anyway.
