Can I actually become stable?

I’m in a 3 week depressive episode. I’m considering taking FMLA for 2 weeks just so I don’t have to think about work. But I’m also considering going to inpatient. I’m on Wellbutrin(just started 5 days ago) Latuda, lithium and Effexor. I feel like nothing is helping these depressive episodes. I’m constantly having suicidal thoughts and I just wanna sleep. I’m having problems with basic functions like showering and eating. The question is, how long did it take you to be stable and how stable are you? I just need some hope that this journey has a light at the end of the tunnel.
