I see others mentioned trying dietary changes. I wanted to say it's worth a shot. When my daughter was not yet two, she suffered an allergic reaction to peanut butter. Then she was diagnosed with asthma, then juvenile arthritis, then uveitis, then ulcerative colitis - over a 4 year period. When she started getting sick and was in and out of the hospital, I was very depressed. My doctor suggested lexapro, saying it was not a major drug and wouldn't harm me. I felt HORRIBLE on it... like a zombie. I wanted to cry so badly to release stress, but I couldn't because of this medication so I stopped it and refused to try any other medications when other doctors suggested it. I knew I wasn't eating right, I wasn't getting exercise and I wasn't getting enough sleep, so I told these doctors that I needed to figure out how to live a healthier life first and then if that didn't work, I'd try another medication. I found the Specific Carbohydrate Diet for my daughter (which was worked wonders for her, by the way) and went on it with her so she would have support. Bingo.... I finally felt 'normal' again. My emotions were no longer all over the place. I had better concentration. The fatigue, anxiety and panic attacks disappeared. I could finally deal with all my daughter's health issues, working full-time and keeping up with household chores/responsibilities.
There is a mind/gut connection and if something is irritating your gut, it could be affecting your mind. The diet we follow eliminates complex carbohydrates because they are not as easy to digest. We eat only grass-fed beef and natural meats (no hormones, dyes, etc.). We don't consume processed sugar, dyes, artificial anything.
Even if you feel the need to get on medication, try making dietary changes too. My daughter's doctors all stressed that the dietary changes would do nothing for my daughter, but now are in disbelief by her test results (she's almost in remission with no other changes to her treatment besides diet). I have never felt more strongly about how the food supply is messing up our well-being/health with all the genetically modified foods, pesticides, unnecessary additives in foods, etc.
good luck with whatever path you take!
