Episode caused by good news?

Hi everybody, fellow bipolar here. For a few days I have been experiencing a roller coaster of emotions, and I don't know where I'm standing now. Currently depressed and with fleeting self harm thoughts (I am not in danger, I have no plans, this is something that usually happens to me during depressive episodes).

I got insanely bad news last week, which I can't give too much detail about, as it feels inappropriate, I can just say that there is legal involvement and very bad accusations.

But the thing is, I feel like I processed those news and since, I am actually making a lot of progress and getting better: I booked a holiday abroad for my birthday, I got a job offer, and I got good news about the apartment I want to rent. Despite all of this, I am feeling like I'm slipping into a bad depressive episode. I almost feel like the positive changes triggered it.

I am so frustrated, because I don't think I can stop this episode from developing, and I risk losing everything if it does. Everything is so heavy and I feel like I am one step from totally crumbling.

Just wondering if you have gone through anything similar, and how did you cope? Thank you x
