sorry to hear about the negative thoughts i my self experience this. i am paranoid about half the time with sad thoughts. hey sun is a great idea. about your energy i am also tired al the time my thyroid was way off , because off all the drugs i take i think. so ask about that maybe. also your meds may be the culprit as far as sleep maybe take the heavyier meds at night if you can and don't already. i worked in a pharmacy for eight years so i know meds can mess with just abut any part of your life. side effects i mean. also too much sleep can make you tired. bye- shelly
