I've found that I have the worst mood swings over the most trivial things. A random mess? Mood swing. A phonecall that interrupted my music? Mood swing. It doesn't happen 100% of the time, which makes it confusing since they're virtually random and I really can't anticipate it. 

This has lead me down a rabbit hole of changing how I perceive life and my relationships at the drop of a hat. My gf who I care for deeply and often see myself being a reasonable/mature voice to, I suddenly want to isolate from and live a hermit lifestyle. My family, who I haven't had the best relationship with but do alright just fine, I want to ditch and live freely with the money I have in my bank account. Of course I know these are not reasonable, but they nonetheless feel like genuine feelings I can't shake off in those moments. 

I found that I've never really managed my mood swings, all I've ever done is realize I'm feeling a mood swing but not showing it, instead keeping it bottled in while I carry on in a neutral/stern manner. 

How do you guys deal with random mood swings that often bring up impulsive/self destructive ideas?
