Dealing with some stuff AIO?

Hey, never really expected to post on here, but I decided to anyways. I've been having these problems in my life that haven't really been brought up until recent. I (M20) have been dealing with some "Family Drama" so to speak, for a while now. This drama has mainly come from my own mother, I dont remember everything but the most distinct thing I can remember was in 8th grade, now keep in mind I was held back a year or two so I was a bit older than everyone else. Nevertheless towards the end of my 8th grade year, I started to rebel like any other teenage kid would, but the most I did was wear a leather jacket and act tough. Yes there was some rule breaking but nothing illegal, just in the eyes of my mother, once she found some messages on my phone between me and my gf (at the time) about her, she got pissed, not only at the messages, but also because I had a gf that she didnt know about, she waited till I got done with school and walked down to her work (it was easier to just wait there since her work was closer than home. Once I got there my mother had waited for everyone to either leave her office or be busy before she started bashing me over the head with her fists. At the time I just shrugged it off (still acting tough) but after all of that and her yelling at me, she pulled me from school and cut me off from everyone and everything, I was basically inside my house 24/7 since i wasnt able to see friends and had no reason to go outside, this lasted for 3 to 4 years, she did slowly allow me to see my friends, and allowing me to go places. To this day, I do still hide things from her, like my current gf (F18), whom I love to death, but after venting to her about this and other things, she brought it up that I have some form of PTSD and Trauma from my mom, which at first i didnt believe, because I was so used to how I was living, that I couldnt see how I could have those things, but after looking back on the recent events like how my mom threatened housing because I was enjoying my freetime for longer than she wanted, and then once I compiled she went back and said that she didnt want to kick me out. Now its today (04/08/2025) and recently my gf offered to take me from my house to live with her, and I've been in deep thought ever since going back and forth on whether I should stay at home of go live with my gf, but I've been seeing more pros than cons when it comes to moving in with my gf, but I'm not 100% sure, so I can here to kinda rant, but AIO? I dont know.
