I am so sorry that you are going through this. I am coming off of a manic episode and trying to keep myself from tail sliding into a depression. It's definitely not easy, and I feel just as you. I unfortunately don't have a doctor, so my advice is based on experience alone. I try as hard as I can to not think about the past or the future. I just try and focus on the now. I try to remind myself everyday that just getting out of bed and doing my make up or showering is better than nothing. I also try and sit in the sun and see the beauty around me rather than dwell in my own dark, depressing, negative mind. Exercise and a routine can also help lessen the discouraging feelings. Now, this doesn't always help, but it has never hurt to try! I really hope this helps even a little, and wish you the best of luck. At the least, just remember you are not alone! No matter how dark and lonely it may seem....
