Needing Some Assistance

Hello, first off, I've never done this before, asking for assistance. Well, I'm a soon to be divorced,  single mother of two teenage boys that are very active in school, sports, friends, and family.  I'm going through a very nasty divorce, where he has caused me to lose my job, my car, and possibly losing my place to live. Now with Christmas here, I'm not even able to buy anything for my boys. If I don't get some help then my soon to be ex will try his best to take my boys from me and I have been the only constant parent in their lives since the day they came into this world. My two boys mean everything to me and I will do anything to keep them in my life. So, now I'm here asking for some help from strangers with the hope that someone will hear my cries for help.
