One quick thing that I would like to add...since the babe is far too young for a strict "feeding schedule"..I would make sure at this point & time, his food should ALWAYS be made available to the youngster...that alone will dismantle the "oh, I need to feed him ASAP method of thinking" right off...which, will allow your pup to have MORE time to spend with you without worrying about feeding & such..again, if there is an issue of how you are spending more time cleaning him up cuz he's messy with his food & water,(you could also go the route of hiding pieces of kibble throughout his play area, which will help keep him occupied some too..a kong toy would also be a nice way to divert his attention)...I would suggest getting a big water bottle that he would have to lick on to get his water..this will eliminate the option of "playing in it"..(my pup considers his water bowl as a water-park ride...yay)...
Another thing you could consider since he is SOOO young, is-allowing someone that you would trust enough to allow into your home to help him out some during those long, lonley hours...or, perhaps, is there someone else's home you could leave him with whilst you are earning your keep??...Sometimes, for the benefit of a babys sake, the use of reliable recruits could help work wonders on a tiny babe...

I DO wish you the best of luck, & hope things do improve for your new youngun' ASAP...for BOTH of your sakes!! *hugs, & luck*
