Comparing myself to others, regrets

I’ve been sober almost a year and a half. However, I struggle to not compare myself to others. Particularly career, relationships, etc. I’m a 31M and I’m an engineer but I have some debt as a direct result of drinking. I’m single and have been since Highschool although I had a couple chances with incredible women to get in relationships over the years. I was just too self absorbed and had a spoiled mindset while I was drinking. I look back now and all those missed opportunities are getting to me today. They are married, look happy, have kids etc. I wasted my best years to liquid dope and it’s nagging at me. Looking for support or similar experiences/feelongs. Thanks!
