another speed bump

This morning i got my son up and ready to go to grandmas for the day while i work only to find that the battery in my car was dead!!  My phone is not working, so thankfully my mom just happened to be on face book. i messaged her and she came and picked us up and dropped me off at work. I wish so desperately that i was able to just go get another car. There is no way i would be able to afford to make any payments at this point, so I'm going to have to try to figure out something else. I wonder how all these young teens feel when their parents just buy them a brand new, way too expensive car? Do they even appreciate it? Do they know how blessed they are to have that privilege? I've never been handed anything like that in my life. Don't get me wrong, I am proud of myself for the things that i have accomplished. I think that if you have everything done for you then you don't really get what it is like to work hard for something and how truly rewarding it is to obtain those goals. However, in times like this i really do wish i had someone that could just step in and fix things for me. what to do now?????
