Time. It's cliched, but it just takes time. Take comfort in the fact that (I think it's safe to assume) you gave him the best life you could on every day you had him. Hopefully your family understands that YOU need THEM to step up for a little bit. TBH, it's good experience for them to learn to take care of some things for themselves. I mean, what would they do if you had to leave for some reason (school, career opportunity, fresh start somewhere else)?
