Re: A little more info please.

You sound just like me a few years ago. I have fibromyalgia, which I believe is not so much a disease as a collective of symptoms of other things. First of all, regarding the medication, if they are all for your bi-polar disorder, think of the last one that helped you, then wean yourself off of any that haven't helped since, one at a time. Then, when you have done that, wean yourself down to the only one that has helped, and go from there. Tell your psychiatrist that you're doing this, and make sure he'll work with you. If he won't, find another one. Mine respects me for refusing to take just anything he tells me to, even though he's got other people on up to 10 meds! The side effects of the meds are so bad, and I am down to 1/2 of a 200mg Lamictal and one Requip a day. I will wean off of the Requip soon, I hope. Requip is for restless leg and Parkinsons, but it has shown promise for depression, and it does seem to help. I can now, though, go just about every other day and continue to do well. Bi-polar disorder is very dangerous I'm sure you know. Please don't just stop your meds cold.
Your IC and fatigue are probably symptoms rather than singular problems. I think that coming off of the meds and changing your diet, along with regular massage (or kinesiology) and gentle excercises will help you tremendously. I still struggle, but my life is so much better now. Recently I started to drink my ACV and baking soda daily again, and I feel better. I also have been taking Iodine, but I haven't had my test results yet.
GET SOME METFORMIN! Yes it's a pill, no, I don't care. Get some. I can't tell you how much of a difference it has made for me. Go to an endocrinologist and get your hormones and glucose and insulin tested. Even if they are 'normal', ask him to get you on the high side of normal, and get some Metformin. I have never been so thankful to get a pill since I got my Lamictal. I have lost 35 pounds without even trying (it took a while, though) and feel so much better.
Lastly, when you've been depressed long enough, you're mind set becomes very messed up. I had to work very hard to change my thoughts and outlook on things. I still do have to. I pray a lot, and I know that if I didn't have a close relationship with God I couldn't have made it this far. I don't know if you are a spiritual person, but I am, and I would be remiss to leave out the thing that helped me the most. If you're not good at 'checking' your attitude, repremanding yourself, so to speak, when you get into a negative and pitying attitude, then put a rubber band around your wrist and literally snap yourself out of it. It helps you become an analytical person, to analyze your feelings and get down to the root of what the real problem is with each negative feeling. Like, where's it stemming from, what are you really afraid of, why are you really angry or sad, etc. It's almost never just the thing we think it is.
So, I hope it helps. I've been to the worst (I hope, any worse and I may have been dead), and I'm here to tell you it can get better. Don't give up hope, and don't be defeated by setbacks. Just keep starting over. And if you do believe in God, pray pray pray pray pray for a relationship with Him.
