Energetic self symptoms and conditions

After the birth of my second child my birth control was switched to Desogen. I have had terrible mood swings/depression, I am tired all the time and I just can't seem to lose weight. I exercised daily at high intensity and I stayed the same, so I just gave up. I am just not my energetic self any more. I have been on Desogen for 2 1/2 years now and I thought it was just me getting older. A friend mentioned that it could be my birth control pill and I started doing research. The more I read the more real it gets. I would like to thank all of you for your postings, it has helped me make sense of all my issues.
