People around you are NOT better than you. For the most part they are faking it and hoping like crazy that they'll make it. In some places, e.g. SF, SV, everybody is "crushing it". It's an act. Most likely they suffer from impostor syndrome.
It is daunting to change everything at once. So just pick one area and make some small improvement. You imply that you are married. That is a good place to start, sit down with your spouse, tell them how you feel and discuss how you could make one change (cooperatively) that improves things for both of you. Then you could repeat this. Having improved home situation is an excellent start. Emboldened by such a success you could have a similar step with a very good friend and so it goes on. I would leave becoming better at work to when you have some wins on the board.
There is no stigma in seeking professional help. It certainly helped get me onto the right track (I was single at the time and hardly had any friends due to working long hours).
