It does sound like you have a plan, which is excellent. Keep learning those skills as much as you can. Importantly, don't abandon your health - both physical and mental. Without your health, there's not much else. It may not be easy, but it's essential that you make some time for exercise and to visit a doctor. This can help keep you stronger longer so that you can travel as you wish to do.

It is within reach. I want you remember that despite your life circumstances, and even if things do not turn out perfect, you still have the power to lead your life in the direction that you're planning, and make the best of the cards you're dealt. You have to be brave enough to make it happen while you're still able to do it. Tel yourself every day, with vigor and sincerity, that this is doable. Do this until you truly believe it - and then do it!
