43 is not really "late in life". I think if you can get your situation evaluated professionally from a physical (blood tests/levels, physical conditioning assay, environment), mental (therapist/therapy) and financial perspective, you can begin to make progress on the goals.
Take some real consolation that many MANY men in their 40's that got married and did the family life in their 20's are separated or getting separated. Compared to that level of social debt - you are still in a very reasonable spot to make moves.
It is very easy to boil it all down to "just get moving", and I understand since it's so far down the journey to turning things around that it's easy to dismiss as well-wishing, but that is really the only way to effect change. Get uncomfortable with your status quo and stay uncomfortable.
Finding success in your 40's is not as easy as it is in your 20's, but you have no material reason not to find it.
