^^ Been there done that. It's like making money, the more you make the more you spend. Sure, tons of good things like saving, etc...happen but in your case and I've been there and go there still, the more you achieve the heavier the pressures in life become. Sometimes you don't know you're lifting tons more but you are.
What's helped me is to simplify things a bit and to go to counseling. I'm not above saying that because it does help. No different than a massage for your body, a good sit down massages your mind. For me it helped put things in perspective and I realized that there were a ton of pressures in my life that I just plain dealt with that my mind and subconscious was not happy with.
Once I realized all of them, I put a plan in place to address the concerns. It's a constant work in process for all of us.
