Hello michela_22, welcome to PC!

I hope you find your time here to be of benefit. Once you have 5 approved posts you will be able to enter the chat room and talk to fellow members. There is almost always someone online to chat with.
That sounds like a frustrating living situation for sure! I would encourage you to move out on your own as soon as possible. I know you worry about your mom but she is an adult and has to look after herself, she can't expect you to cover her expenses. Do what is best for you and your mental well-being.
