Really stressed out

I’m going to have to withdraw from my class and I’ve been trying so hard to do well and I’ve studied had a study group and nothing i do is working. We have 3 grades and 2/3 for this semester I’m doing trrrible. I’m taking accelerated courses and i go to school full time and ALL OF THEM are so hard. There’s a lot of pressure on me at home to do well in school and I’m not doing well and I’m really disappointed in myself and i know my family will be too that i have to withdraw. This semester has been awful, every class i have is way too fast and i have to work to pay my bills. I just want to stop going to school. I’m so frustrated
