To ask your advice?

[Sandbox]

I’m restless, I’ve never stayed in the same place for very long and I’m bored and restless. My son needs to be settled, needs routine and time to develop relationships with others so I can’t travel or move.
So what can I concentrate on or do to get me out of this rut?

Get a hobby...one that is progressive like martial arts

This is going to come out very harsh, but you’ve already said what you need to concentrate on to give your son stability. Him.

I think you need to be working out why you are always restless, bored, can't settle for long etc. Perhaps therapy?
