34 Years old with terrible decisions. Need help.
For background, I'm M34, and I'm trying to turn my life around. During university, I was a part of a frat and fucked around too much. Resulting in getting a girl pregnant. In addition, I made terrible financial decisions like buying exotic cars, racking up child support loans, maxing out my credit card, and ignoring payments for my student loans, resulting in ~400K debt. Luckily, through my network, I was given the opportunity to work in a big tech company with a starting annual salary of 149K, but I don't have time to research and manage payments. I won't be giving my family's situation as my wife and I decided that it was best to separate our finances so nothing would affect our child.
E55 AMG Loan ~ $28,800
Child Support Loan ~ $9,000 (prioritizing)
Student Loan ~ $125,000
Bank of America ~ $7,000
Mortgage ~ $298,000
I wish I had never made these terrible decisions, thinking that I could live like a king, but now facing reality. I seriously need suggestions on how I can manage this or resources that can help me.
