I've experienced my own version of this once before, where I lost a girlfriend (and distanced myself from friends and family) but ultimately it didn't work out. My advice is to remember that it's a marathon, not a sprint. Unless you nurture and protect the important relationships around you you will burn out and the recovery from failure if it comes will be that much longer. If you are 22 or 23 a girlfriend may be less important, but remember to invest time in seeing your friends (non-company!) and family. Prioritize time as a concrete thing that will keep you refreshed and energized over the long haul.
