We're allowed to screw up. Your parents love you. They want to take care of you. I moved back home when I was 27 and pregnant. My husband was in basic training and we had to sell our house so I was homeless because we didn't have another home yet. My parents took me in, no questions asked, and took care of me. That's what parents do. You aren't a failure, you're doing what you can to get your life going. There are going to be hiccoughs along the way, that's life. Hang in there, everything will work it's self out.
Everything will be ok in the end. If it's not ok it's not the end.
