My personal experience is that when things start getting better, always question whether it is really getting better or is it just the manic phase. I have stopped taking medications twice when I started feeling better, only to crash a month or two later.
What worked for me was fixing the depression phase (the more concerning one in my case). I started working out and it killed my depression. And mania never came back. I am not taking medication since at least 2 years now.
Of course everyone is different but you have to try. I know it is very easy to succumb to hopelessness because everytime you get better, you get worse but it is manageable.
That is cold. I wouldn’t think that even about my enemies.
