I feel for you dude. I've been fighting depression for the last 25+ years. Specifically bipolar depression that only got diagnosed correctly 6 years ago. Before they just said depression until one therapist asked the right questions. My pops was very depressed as well so I got it off the old man. It's almost impossible to get out of bed some days. I did the drinking away the pain thing for a bunch of years at a functioning alcoholic level, until I wasn't. The drinking thing is a vicious cycle. It does work quite well - in that it does provide temporary relief while you are buzzing, but then it wears off and it's a depressant.
I've tried so many different mood stabilizers in the last 6 years - first only generics due to lack of good health insurance, then the newest ones due to better health insurance and free samples from my shrink because with a deductible it would still be a pretty penny for the first 2 months of meds. The meds thing is like throwing darts blindfolded. You take one, gotta try it for x amount of time, see if it helps with current depression or prevents future depressive episodes, plus encounter any side effects. You see what it does, weigh any pros with any cons, then try another. Only one pill did much of anything good on the mood side but made me gain weight. The weight gain or sexual side effects are the two most common, although I had a couple other side effects with another. So I'm on something else now to see how that goes. My buddy out in Denver is trying Ketamine therapy, I'm thinking about doing that as well. I've tried Lithium, Lamictal, Latuda, Abilify, Geodon, Depakote, Vraylar, and then Neurontin for anxiety. Anyways, it's crippling.
One of the best things I did was get a dog some years back, he gets me out of the house and walking and some companionship. He's a big dog, 62lbs, so needs long walks. Sometimes that first walk can launch me into a better day. My love for that dog and knowing he needs that walk makes me get out of that bed. Stay close with the family you have, I know you had a loss recently but seems you have some others nearby like your niece.
