As far as the psychosis it helped me normalize like I’m still an ok person because that’s not what I was thinking...I had a huge self stigma. It didn’t really help me recognize the psychosis though only meds helped with that. For me I don’t recognize mania until psychosis because it’s work oriented up until and even past that point.
As far as depression it seems to work great, I get minor dips and can get myself out of them before they become severe. Self care is most effective for me. As in do three fun things with three different senses all at once. Turn on the Christmas music with faux fire and eat or drink something comforting, for example. Basically I learned this technique from my cbt therapist, she was like if one thing is good do two....I upped it three because it works better.
