I am giving up

3½ years ago I stated a POS business, which was going on well and I am always thanking God because I am the bread winner of my family. I never believed in spiritual attack until last 2 years when another guy opened a POS beside me, my business went down drastically. For 2 years now i have been battling with mysterious debt because I don’t know how I got to be in debt. I can’t go out, I can’t buy things and I don’t even know how to beg. I don’t know where to start from again, I think I am giving up.
