I stole $40 from my mom today

I (22F) stole $40 from my mom today. I was at my parents for the weekend and was getting frustrated with how they have been treating me and the financial situation. I stole the money because I had some debt I wanted to pay off and I didn’t want to have to borrow money from them to pay for it. I feel terrible about it and I don’t know how I can ever forgive myself.
