My twin sister passed away I need financial help I'm in debt trying to support my nephews.

My twin sister passed away 3 years ago very quickly of cancer at age 45. She has two sons 10 and 14. I had worked two jobs but quit the second when she was diagnosed, we were extremely close I went into severe depression when she died. I lost my sister and best friend. My nephews are like my own kids I don't have any of my own. I have used credit cards to pay bills and then used credit card to pay off those credit cards. I'm trying to take care of my nephews the best I can. I want to help them out they are having a very difficult time dealing with there Mom's death. Her husband is disabled he was hurt 7 years ago on a barge and can't work. I'm single and with my income I just can't do it anymore. I'm turned down for loans, I'm behind on all my bills and my mortgage company is threatening me that it's going to go in foreclosure. My power was turned off for two days because I didn't have the money to pay my utilities. No matter how carefule I am I always get hit with insufficient fund charges from the bank. Today I have $1.96 in my checking and don't get paid until the end of the month. I work a lot of hours but don't get overtime on my job. I don't know what to do anymore. Our family is hurting so much since we lost my sister. I won't ask my parents for help there elderly and I can't burden them with my debts. I'm thinking about bankruptcy but I really don't want to go down that road. I work hard but still get further behind. I would be so grateful for any help I could get. It's not my nature to ask or beg but I don't know what to do anymore. I would really like it if I could help someone out some day.

Please I need your help.
