Not going to go home after school, any tips?

Mainly only doing this to scare my mom into getting an actual apartment. I can’t stand this place. I’m homeless and have to shared a small hotel room with one bed with my mom, adult brother, and me. I’m only 15 and already been homeless for like 2 years. My mom is extremely strict and won’t let me do anything. I can’t go out by myself, can’t go out with friends, and we can’t go out on weekends so I literally go from school to back to this tiny hotel room everyday. My mental health keeps getting worse and worse so I just decided I won’t go home on Monday. (Is that even considered running away? Oh well.)

I don’t really have a plan or specific outcome, probably , probably just go to a lake nearby and clear my head. I feel like my mom will report me missing but I don’t care atp. Worst she can do is take my phone. I barely hear about crime in my state so I doubt anything bad will happen to me. Plus, this is the only thing I know of that can potentially make my family get us out this situation.

Gonna try to take some pepper spray or something if I can even find it.

Any advice is appreciated. I’ll probably come back at night. Let’s hope I don’t get kidnapped! Wish me luck! (˶ᵔ ᵕ ᵔ˶)
