Those 13 months that you became a full-time musician weren't wasted. They were probably the perfect remedy for all the cr*p that you'd been through before. And just because you need to get a non-musical job, it doesn't mean that those months were wasted - you'll always have the skills & experiences from that time.
As others have said - don't think of relegating your bass playing as a hobby behind a day-job, the day job is the hobby that pays for bass playing.
