Anxiety at an HIGH POINT

I don’t like being home alone, never been a big fan of it. However I have been home alone more times than I can count on both hands and feet. Recently being home alone has my anxiety at an ALL TIME HIGH. I’m hearing things, I’m paranoid (every time I leave my room I’m looking in corners and keeping my head on a swivel), carrying screw drivers etc. These fireworks aren’t helping at all they are soo loud and sound so close, it sounds like a mixture of fireworks and gunshots. I’ve been trying not to cry but I can’t help it. Even when my mom came home I wanted to cry. I know this might sound so stupid that a 17 yr old can’t handle this but it’s my truth
