How do you cope with the mood swings?

I have been diagnosed for around a year now, and am relatively young. I had a variety of substance use disorders as a teenager, and am now officially a year and some change sober from pills. I have a job I’ve been able to maintain and managed to get certifications within the medical field, but I’m struggling every year with these intense mood swings. I was hypomanic the last few weeks, but it’s uncomfortable. My body starts to feel overwhelmed, I get angry a lot easier and I feel like I’m on a rollercoaster just sitting still.

I’ve now began to transition out of that and into a depressive episode. I’ve gotten good at noticing this, because I begin to feel like I’m underwater. I get super exhausted, like my brain can barely process normal things like driving. It’s a huge gap, but I don’t wanna do anything. I just wanna sleep and cry and do nothing. This has turned into a bit of a rant, but I genuinely don’t know how to deal with it. I’ve tried a couple meds but they didn’t really work, I suppose I gotta be more consistent with that but like I said it’s still really early into the diagnosis. Is there anything you guys do to be more consistent with life? I feel so defeated. I just turned 19 and I feel like I’ve been battling with my own self for years now.
