Frustrated, stressed and losing patience..!

So our back breaks went out on our car. 2 weeks ago we just put $150 new back tires on the car. My mom thankfully is taking me to do the running I need to get done and of course doctors appts for me and my son. I have a car payment to make but haven't been able to drive my car last part of week and won't be able to drive it at all next week as Hubby gets paid every 2 weeks. I feel it's pointless to pay my payment this week as I can't us my vehicle or get it fixed til next week.(prob will end up paying it) we want to go next week to buy a vehicle out right at a buy here pay here and it's about an hour away and can't find anyone to take us. I'm so stressed and frustrated with everything that's happening and not to mention I am 36+1. Im trying to keep calm but its becoming impossible! Plus my mom and I were texting and she wanted me to get ahold of a couple places to see how much they would charge for back breaks and I got false hope about that and asking if she would take us up to get a vehicle. I'm over everything at this point honestly. I hate relying on people and we don't have much family(hubbys side doesn't help as they live half hr away) and my mom does help with what she can but nothing financially which is fine. I have one friend and she lost her license and Hubby knows a few ppl at work but prob won't be able to help. I'm done!!!
