My life is a mess..

Hey..
So I don't know who is reading this, if anyone, but things aren't going that great..
My neighbours are violent people and have no respect for anyone, and they have been making threats, verbally abusing me and my siblings, aswell as my mum, and have honestly been scaring us all to the point of wanting to move house. If only it was that easy, except you need money and an actual decent place planned out before you get to that point, and we have neither. So for a little context, my mum made a noise complaint several times about our neighbours, and the police eventually stepped in. Clearly, they didn't care and decided to, overnight, slash our car's tire. How did they know we reported them? We don't know, they realistically just assumed. But since then, they have been completely unapproachable and have even gotten to the point of attacking me in public. Only minor things such as shoving, jumping on, etc. But this is just really scaring me. I can't sleep at night anymore. My mum is going into surgery soon and we'll be alone in the house, and they might do something. We have told the police, but they're so useless and don't want to help. They say they can't do anything until they do something again. It's so stressful.. and ontop of all that, school's coming back soon, my friendships are falling apart, I never want to get up in the morning, and I'm just sad all the time.. My life is simply a mess. Is it worth trying anymore?
