Reckless thoughts and mood swings

Lately I feel like I’m losing my mind. I just want to do reckless things (get tattoos, piercings, vaping, drinking, etc. that I’ve never been interested in before but all of a sudden want it done like right now). I lost interest in all the things I usually like. I broke up with my boyfriend of 2 years for no solid reason and have been flirting with multiple people around me that I KNOW I have no real interest in. For about a week or so I was really hyper and happy over nothing but now I feel really depressed. I get really annoyed by little things. I can’t sit still or focus on one thing at a time. When I look in the mirror, I don’t feel any connection to the person there. I overeat and oversleep.

I want to get help but I also feel like I just can’t bring myself to admit the reckless things I’ve done.
