Carl I can understand your reservations about turning to your son, but as Jim said, it might help you both to grow and progress. Who knows, it may even become the bedrock that cements your relationship going forward. I have 5 sisters, and I've never really been close to any of them. Not because I dislike any of them or because I don't get on with any of them, just because I'm the youngest boy of my family. I don't really have much in common with any of them. They're into talking about diets, hair styles, cooking, gardening, fashion, and what not. I just like footy, shower masturbation and oral sex, so we don't really have much common ground. It's not as if I can say "hey Sis, listen to this, I tried to lick the box of my boss". It would probably be about as well received as Gary Glitter taking a dip in the kids pool at Butlins
But my point is this. They are still my kin. When I needed them, they came through for me big time. Despite the fact that I was never close to them, none of the 5 of them ever turned their back on me. That's the beauty about family. You can forge strong bonds with mates, but family bonds are different. I'm sure that despite the current wedge between you and your siblings, behind it all they still love you. I'm also pretty sure that if they saw you making a conscious effort to help yourself then they would oar in behind you. Same goes for your son. You're his Dad. I'm sure he loves you. Reach out to that love if you can lad. Bit by bit, if you show you're at least willing to help yourself, then I doubt that they would ever turn their back on you
