i'm the same as you mate, except for i haven't taken meds since last year, and i always seem to be going up and down and finding things to make myself feel better and as usual, one day they go away... which happened last week so i'm all lost again.
i just try to keep myself distracted, and lately more than ever i'm trying to not be alone because i let myself isolated all my life and i now i regret it very deeply. watching things make my mind get away from itself for a while, so i'm always watching something, mostly series, last year it was loads of anime series. i think reading does help a lot too, i should get back to reading. and try to go out, even if there's nothing specific to do, make yourself feel better, not in a "get healed" way but for the moment you know?
and know you are not alone. knowing i'm not alone means a lot to me - tho sometimes i desperately seek to feel that i'm not alone... we're on the same boat buddy. wish all the best for you
