Cycling in depression

Queen 👸🏽

I go so good for a couple months on the top of the fucking world and then spiral down to this scary sad place again. I’ve been on every drug cause I’ve dealt with this for years and none of them lasted long term. I tried moving somewhere sunny, it helped but didn’t solve it, I try staying super busy and I try relaxing as I feel my anxiety and depression creeping up on me. Does anyone have any idea on how to stay happy? My life is seriously so incredible I have nothing to be down about.
