I feel sad...

I truly do feel like a horrible mother because money is tight, and I feel like even though my daughter has everything she needs, it's not enough.. I get so sad that I can't give her the most expensive things, and at that I share a room with her, she only has a little corner and it truly makes me feel like I failed. I never felt so horrible.. I know I'm trying, I'm 17 years old. And for my age, I know I can't even get a home to give my daughter her own little room to start with. I just feel like a failure, today I was even shopping for little headbands and I bought 9 of them for a dollar. Deep down I felt heartbroken that I couldn't get the 6$ ones with better quality, all I'm doing here is sharing how I feel. Maybe someone else feels what I feel
