For 6 years I’ve struggled with extreme exhaustion for no discernible reason. It’s like the life force was drained out of me. No matter how much I sleep I still feel the strong need to sleep more. It strongly negatively affects my focus and concentration, as well as my ability to be social, which brings me a lot of guilt when it comes to my family and literally not having the energy to keep up with them. You may say it’s just a side effect of my depression, but I’ve had depression for 11 years, meaning I dealt with depression 5 years before the constant exhaustion set in. Furthermore being on antidepressants did not improve my energy levels whatsoever, despite stabilizing my mood. I’ve gotten blood tests for numerous different things and all came out clean, I made significant lifestyle changes and regular exercise did not help, healthy eating did improve it somewhat but did not fix it. I have done everything short of go into an actual sleep lab and I am going to request this at my next doctor’s appointment because I am absolutely fed up with not being able to live my life and function as well as possible because of this pervasive, mind numbing exhaustion. If anything it’s gotten worse because I’ve stopped doing so many things in my life because of it. Horrible.
I know exactly how you feel…
Despite my attempts to increase my energy levels, it feels as if I’m never going to get out of this fatigue cycle.
However, my med change actually helped a bit. I’m hoping my faitgue isn’t chronic and I hope yours isn’t too. Have faith! 
I’m tired all the time too. For me, I was recently diagnosed with hypothyroid ,which causes fatigue, and , of course, my antipsychotic makes me tired too. My life would improve dramatically if I had more energy and focus. I am so f**king drained all the time. I go to sleep at 1am and don’t get up until 11 and then I sit on my a$$ all day. I go back to school in 3 days and I have to get up at 10am and I am all worried about that. I will, literally, have to take my meds at 10pm and be asleep by 11/11:30 to get up at 10am. It’s pathetic. I need to start volunteering at the Hospital (500 hours) to be able to apply to the program I want next year and I don’t know how in the hell I am going to get it done and go to school at the same time. I was only recently medicated for my hypothyroid so I am hoping the meds will kick in and make my life easier. I drink coffee every ‘morning’ so I am getting what I can out of that. I dunno? I feel your pain. I hate being tired. I am missing out on life.
I remember when I was in washington dc. While I was there for some reason I was always tired in the mournings. That and I couldn’t go to sleep at night either. Although this probably fall more into insomnia for me I guess, but I think I was getting 9 hours of sleep a night but was still tired.
I can relate. I’m often tired because I have a hard time sleeping. When I go to bed I’m doing good if I fall asleep in two hours. I know what a grind that constant fatigue can be. I’ve always tried to handle the lack of energy problem by doing large amounts of caffeine. It helps to anticipate your body’s sleep rhythms, even if they are hard to predict. Try to schedule important events after the nights when you sleep well. Maybe if you are in another building than your home you can grab a quick nap or two by resting your chin on your hand and your elbow on a table. Keep searching for a sleep specialist who just might be able to help. There is a drug called “amytriptline” that can restore sleep cycles. It is a tricyclic antidepressant combined with a sedative. It worked for about six months for me. In a way I kind of missed the time I spent laying awake in bed ruminating about the world’s problems. You might learn to do that yourself - to close your eyes and rest, and keep yourself entertained by your own thoughts. That’s what I do, and I’ve learned to enjoy it.
Loss of vital energy is well described by psychiatrists as symptoms of sz. It is part of negatives.
I’m feeling drained by certain people especially my mother whose Hodgkin’s lymphoma from 11 years ago has returned. She really has no one else in the area that can help her. Music especially new has even lost it’s appeal. But unlike you others, I’m hardly getting any sleep and I’m missing meals and medication doses. I guess the one thing I’m finding hard is having meaningful relationships with anyone whose interested in being a mature adult in the 21st century. I think I’m lonely.
