Lots of practical advice in the comments, so I don't have much additional to add
Aside from the pharmacological problems, here are some additional items.
(1) Have a doctor determine if you have hypoglycemia or hypoglycemic tendencies. This is the flip side of diabetes, and is a tendency to low blood sugar or to rapid reductions in blood sugar (overproduction of insulin). The brain cells can wind up starving and the mood swings can be intense, going far into depression and darkness and nausea. About a third of hypoglycemia cases are initially misdiagnosed as mental problems, when they are only a blood chemistry aberration. There is a phenomenal repertoire of symptoms.
(2) On the psychological side, it is absolutely essential to keep your attention OUT. Do not become isolated or inward. Take walks outdoors. Watch a good TV program (rare) or motion picture (rare...but the oldies are goodies). Try to notice Beauty anywhere in the world. Be on the lookout. The existence of beauty is real---and a refutation of any grim spirit that is haunting you. The more you look for it, the more you will find. (My favorite is clouds.) The more you find, the more you will realize that this IS the way of the world, and the grimness is just another one of Satan's lies.
(3) If you have friends or loved ones, try to be with them and learn their trials and sufferings. Sometimes, it is better to replace self-pity and agony with pity and empathy for others. Consider your blessings---that you are not crippled, blind, deaf, or maimed. Look up the Journal of Reconstructive Surgery to read case studies of people being corrected from dreadful conditions. Truly, there are worse things to endure, and---though it may be trite to say so---it is in pity that we begin to appreciate our blessings.
(4) Make friends with animals: Dogs. Cats. Squirrels. Horses. Goats. Any mammal. Seek any level of communication or reciprocal response. (I'm not against birds, reptiles, fish, or insects, but they have very limited responses to human overtures.) The more you give, the more you will receive.
(5) Make plans and carry them out. Nothing is worse, spiritually, than to have a life made of nothing. Determine that there is something more important in life than being miserable. It doesn't mean the misery goes away, but it does make the misery less important. (This is where reading Russian novels comes in handy. I was going through a spell of depression and was lifted out of it by reading Solzhenitsyn's "Cancer Ward." An odd pick, but he had a way of showing how people facing death found more in life than the usual person.)
Okay, that's it. I hope it adds to your resources.
