Am I the drama? A lot of ranting

So my mom has put me through a lot of trauma and I get over whelmed and stressed when I am just in her presence. She has dated asses which matches what she is. but her gf she has now is a little better then everyone but the both of them don't think I am mentally ill and don't think I need help. I have not been diagnosed with anything but my friends who have been have told me it is pretty obvious I have some sort of adhd anxiety and depression. recently I think I may also have bpd but idk because no one wants to get me signed up for a therapist or anything. I am 17 I turn 18 oct 25th but I started smoking weed which helped with my stress and helped calmed my nerves. until I ran away and my mom went through my shit and saw and I went sober for the rest of the summer which was a true experience. But I ended up stealing my moms gfs kart. I was caught being completely stoned and out of it. I had smoked before I was gonna finish my chores and then lay down so I could sleep easier but it didn't work out. I know I could have went a better way about it then stealing but my mom isn't wanting to just let me move out and be in a space that doesn't make me wanna unlive myself. But now I have to apologize to her girlfriend which as heartless as it seems I don't feel sorry. I just can't feel remorse for what I did because of how shitty I feel around these people 24/7 and they don't wanna help anything and just make it all my fault and say I just don't wanna be "normal". I wouldn't ever just steal from someone. But I had been so stressed out and unable to know how to help myself so I took something she hadn't used in 2 years because I remember them getting this while I was in 10th grade. It was something I thought they would not think about. But then I was being threatened and I wasn't wanting to get my jaw broken so I finally told my mom where I got the kart from. I know it was a dick move I just don't feel like the dick in the situation.
