Since your H is at work during the day anyway, can you pick up a second day job, or pick up more overtime?
You are hardly putting anything extra on the loans. Your salaries should go up if you move in a year for higher paying jobs, but you will likely have higher housing costs as well, and you need to be planning for car expenses as well (we had a '99 Corolla that burned oil like crazy...... it eventually got sold for 900$ at 180K miles when it was on the verge of total collapse).
Ditto the others to get rid of that cell expense. At your income level (9$ an hour jobs) you really can't afford a smart phone at all. At most you need super low data pre pay plans that are for emergency use only.
In my rural area with low paying jobs, we have warehouse jobs around 9-11$ an hour, more if you go through forklift training, and nurse aide jobs around 10-12/hour. Unless you are really rural, I am surprised you can;t increase your salary by finding a new job. Unless you are working part time, in which case also find a new job!
