How can pelvic floor issues be caused by this 😭

I never even thought that masturbating can be this dangerous 😭😭 I'm a 17 year old teen and I'm so scared right now. So I masturbated as usual and I started getting these weird symptoms WHICH ARE NOT GOING AWAY SINCE A MONTH. My abdomen is so big and bloated, my back hurts, I get weird mild pain in my lower left abdomen and and in my left leg too. And the thing is that my left vagina feels more sensitive than the right one which is so weird. And I feel like I've ruined my body and my future sxual life by this as i've researched and read that it's hard to fix a pelvic floor dysfunction. I've ruined myself at such an early age and I can't even tell anyone about this. Idk what to do I hate myself
