Help me get back on my feet

Hey everyone. All of you who know me know that I am a very private person and I never ask for help. However this year has been especially rough. My husband and I split in February. I thought it was friendly until recently, but more on that in a second. I had a miscarriage in April, after putting my body through hell for months taking fertility treatments. With the pandemic going on and the fact that I’m a full time student, I have not been working. The agreement between me and my ex was that he was going to pay for my car payment and the insurance until January. His income is roughly $5,000 a month. I’ve been paying him $200 a month for me and a friend’s cell phone (technically she’s been lying it, since I moved in with her), and the agreement was that once the contracts were up we would get our own plan. That would happen in Spring of 2021. So far he’s messed everything up. He canceled my insurance switch no notice. Then he cut off the phones with no notice and we were forced to get a plan early. We’ve managed to recover from those set backs fairly well. However the car payment is the issue. 

I got an email from my finance company last week. Keep in mind, he has all of the account information, all of the login information, and he specifically had them not calling me. He has been messaging me for months, every month, stating the payment was made. He was lying. I am now three months behind on my car payment. My dad managed to help me with one payment, in order to keep my car from being repossessed. But I was not expecting this, and I am not prepared for this. I am a full time student. I just got hired on at an $8 an hour job yesterday, but I desperately need help to pay the past due on my car. If anyone could help that would be greatly appreciated. 

Thank you!
