Help?!! What could this be?!

So recently (i call this a high) i am experiencing elated moods more of an irritable louder more adhd and anxiety before this (I was having what I call a low) I was having clear depression signs. The day my “high” came back I was having a shitty few weeks due to one of my family members abusing alcohol, but these moods last for months, I can go into detail.

What could this be??!
