I generally browse the UC boards as well (diagnosed w/ UC in 1993). I have probably had some mild forms of depression/anxiety building over the past 5-7 years. However, I have always been hesitant to seek help, get and official diagnosis, or take prescription meds (daily Azathioprene is quite enough). I have dabbled in St. John's Wort, without much success. I have tried L-Tyrosine and other amino acids....nothing. A few weeks ago, I began taking SAMe. I have noticed some effect, a little more energy, clearer thoughts. From what I understand, SAMe is gaining credibility that exceeds other "herbal" remedies. Nevertheless, I think you are on the right track in seeking profesisonal help. I haven't been able to make that move yet.
I also take Fish Oils and B-Vitamins, which seem to help with my "guts" and energy levels. Honestly, I think the one thing that has the most impact on my psychological status is exercise. When I run or workout, I feel a lot more energetic and productive.
I hope things go well for you. I am a bit new to the on-line "forum" situation, but I have really found it helpful. I wnet many years without mentioning UC to anyone, even close friends. Talking about
it really makes a big difference. Good luck. It would be cool to hear how you're doing. I think my email pops up with my signature. If not - email@example.com
