I found finding a supportive, compassionate community a great comfort. For me, that meant finding & making friends with people in a similar situation as mine, going out for coffee, lunch or dinner with them every so often (~2-6 times a week), and using them for support when the roller coaster was dipping fast.
Of course, finding such a support system is easier said than done. I was fortunate that many of my former coworkers were in similar situations, so I just reached out to them. I haven't had as much luck in meetups and conferences, but perhaps you may. Friends of friends were sometimes a good source too - whenever I heard that such a 2nd degree connection was also an entrepreneur, I'd invite them out for a casual coffee and make sure they knew I wasn't out to get anything from them, apart from meeting fellow entrepreneurs and perhaps finding a sounding board. A few worked out, most didn't though.
I should add that I personally find great comfort in being able to help others too. So in reaching out to these people, I sometimes found myself helping them as much as I was being helped - and that reciprocal relationship was what really made it work, IMO.
Another idea: See if you can rebalance your life to include more of your family and friends again. I know that's not always easy in a startup with insane deadlines, but you can start small. Put aside one day a week for family & friends. Or even one meal a week. And make sure you stick to that schedule too.
Debt is another matter, unfortunately. It took a lot of financial discipline to work down my debt, but after several years, it happened.
Hang in there. You're not alone. There's a huge community of entrepreneurs riding the same roller coaster. (One friend told me it's like being manic-depressive; I totally agree.) I hope this helps.
