I'm not sure what country you are in and it's understandable that it's hard to find help in form of foodstamps for a young single man but in the US and I'm sure most first world countries, there are food banks and churches willing to feed you. Most cities have them set up in the central part of town for easier access. Also reddit has a few subreddits about frugal living and even places to find financial help. I haven't read them too indepth but on my cruising for funny cat pictures I've seen they exist. 

I wish I could help more other than to tell you to keep pushing and don't be too proud to ask for help if it means you not starving.
