I feel like a failure...

I’ve made the decision to move back in with my parents. I’ll still be going to work but after living alone for two years I just feel like I failed. I’m 20 years old and I was so proud of myself for doing this on my own. I thought I was doing well so I finally bought a new car. Almost immediately after that I learned my rent was almost tripling. I can afford to stay where I’m at but that’s all I can afford. I’ll never be able to save enough to go to college or buy a home. I won’t be able to do anything I want. I know it’s a good decision I just feel so down about it. I needed to vent about it but I don’t want to hurt my moms feelings and make her think I’m not grateful. I am. I’m just upset.
