How To Deal With Mood Swings?

I’ve officially gone 4 days without using porn and one thing I’ve noticed are these crazy mood swings. One minute I’m happy and convinced I can take life by the ‘you know what’s’ and everything is gonna be great from here on out, then suddenly, I’m reminded of every cringey thing I’ve ever done, all the relationships I ruined, and I think very low of myself.

Has anyone else experienced this? If so, how do you deal with it?
