My SO has ADHD and Bipolar Disorder/ Need Advice

So I need some advice, I actually don’t what kind of advice I want. My girlfriend has ADHD and Bipolar Disorder, she normally takes her medicine every day and that usually goes well. There’s like a certain period where she gets majorly depressed and it’s just hell. She’ll get mad at nothing, at everything, she’ll get pissed off even when she can’t find the other shoe. ( something small but yeah it’ll set her off ) we’ve been together for two years and I’ve dealt this her crazy mood swings and during her aggressive stages and I’m a very patient person and I don’t think I can last long. When she’s mad NOTHING will calm her down unless she breaks something, we just moved in together a month and yesterday she broke the window because she didn’t wanna go to work and I’m just feeling overwhelmed. I don’t know what kind of advice I’m looking for but I don’t know what to do, I try to suggest stuff when she’s in those moments but nothing ever works.
