A friend of mine suggested that I take "Super Vitamin B Complex". She told me that it would give me energy and help me focus. I take one pill a day, in the morning, after I eat. It does not give me ANY energy. In fact, it slows me down. I focus only because I'm in such slow mode that it's all I can do. But the worst is that I feel like crying all of the time. I feel terrible about myself. For instance, I keep having thoughts of how worthless I am and what a failure I am. Even when nothing is going wrong, I feel like crying. I constantly feel like giving up and I really don't know why. Am I having some sort of reaction to it? Does it make sense that I feel this way on it? I quit taking it and I feel fine again (except I'm having difficulty focusing!)
