Unless you are abusing AD's addiction is not an issue. Like any drug that penetrates the brain/blood barrier there is a proper way to start them, take them and wean off of them.
Depression that lasts for more than a brief pocket of time (even if situational) is not something you can "snap out of" quickly. Partner financial stress and all the other stresses that a divorce produces and you are suffering needlessly.
Your brain is "trained" right now to be depressed and the AD's will help retrain your brain.
There is no "high" but if they are managed properly you will begin to feel balance.
