In need of help getting a motor for my truck

Hello my name is CoCo. I'm a single mother and a nursing student. Two weeks after I started school any and everything went wrong. I have been strong and have rolled with all the punches. I was homeless the first few semesters cause my job would not work around my school and I had to get another job. But thank God I got another place to live. I still did give up. I'm very determined to finish so I can provide a better life for me and my kids. The only thing I'm really struggling with now is my motor went out in my truck two weeks after I started class... I had to drop down to one job and I'm just not able to come up with the money to get it fixed I would be so grateful for my truck to get fixed. It would make it so much easier, and would take a lot of stress off me. I'm struggling to get back and forth to clinicals and work. I will be so grateful for any help!!
