I had hefty depression after just a month or so of meth, it lasted just a few days though but I was almosr locked into bed. Caught my by surprise because methylphenidate was never remotely as bad. Ran out, so not possible to source new material.
I would advice to taper if possible, can take you a big amount of unpleasant time. Thing is you don't need the full dose of stims to feel ok, maybe 1/2 of your usual dose or less is enough and then reduce every day or every other by a little bit, allowing your receptors to heal underneath.
