general health and treatment

Since I lost weight rapidly before being diagnosed, I am wondering if this is a factor in whether I will respond well to treatment. I have a digestive problem that I think may be hampering my body’s ability to produce neurotransmitters so I’m trying to improve my diet and including some supplements to try to ease things along. The weather and amount of sunlight seems to have an effect on me too but I can’t change that except to try to get up at the same time even if I haven’t slept well the night before. I don’t want to overthink this as it is part of why I’m depressed.
