I need some help don’t know what to do

Sarah

So I was diagnosed with bipolar 2 in November 2018 since then I’ve been hospitalized 3x for suicide attempt & thoughts. They’ve tried lots of drugs and nothing worked until I tried lithium. They checked my blood levels because it could be toxic if the levels are too high and it was actually too low. They didn’t do anything because I was doing really good. It’s a month later and my mom thought I was acting manic for two weeks. Which I didn’t notice. And now for some reason I’ve been feeling depressed and suicidal but I don’t wanna tell anyone because I don’t want to deal with another med change. Please help me idk what to do. Is this even normal to start feeling depressed again?
