I just need to vent because these past few months have honestly been awful and I don't know what to do because I've been frustrated for the past 3 days straight.

So about a month ago my mom was diagnosed with breast cancer and it's been incredibly hard working full time (I work 3 am shifts) , going to school full time and now running her errands. I'm always tired and I always feel like crying. My mother doesn't deserve this, nobody does. Seeing her sick and in pain is the worst thing I could ever see. Also, I got a ticket for speeding a few months ago and my dad recently found out and now he's making me pay for tires that need to be replaced and other things that need to be fixed (all of this will be coming out to $500), and I have to start paying for all of my car (which is $325 a month). And to top it all off, my best friend and I were walking our dogs in our neighborhood and a large, aggressive dog attacked my dogs! The dog attacked my girl dog first and then when I let go of the leash for my other dog by accident, he went after my boy dog (they're both puppies). My best friend was carrying her dog because her dog doesn't get along with other dogs very well. They're all okay but that was the scariest thing I had ever witnessed. I was screaming bloody murder trying to get my dogs and all of my neighbors came out to see what was wrong. the owners of the dog were trying to get him and when they did I said "is this your dog?! He attacked my dogs!" And the owner's daughter just laughed and turned away. You have no idea how pissed I was. So I followed them to their house and talked to them calmly and said "if something happens to my dogs I WILL be letting you know." And he was understanding and said "I'm sorry my kids must have let them out by accident." But like if they let him out by accident, why didn't they tell their parents right away? That dog was very aggressive and could've hurt mine and my best friends dog. I filed a police report and now they're being fined by animal control, so I guess that's good but I'm just traumatized. After everything that's happened I don't know how to stay strong. I feel like my life is going down hill and it's only gonna get worse. I've been having negative thoughts and been wanting to cry almost every day. I feel like God's testing me and I don't know how to stay strong.

Thank you for those who read this, I know it's pretty lengthy.😭💕
