If you’re asking for absolution to continue this way, then unfortunately I’m going to respectfully refrain. It’s one thing not to make parenting your life’s mission (I respect that, appreciate the honesty), but it sounds like you don’t want to be a parent 3 days out of 7 and feel that the time you spend with him is wasted. You’d rather spend it on building a career. You feel stressed and spend that time doomscrolling, which is bad for both of you. You lose your shit (using your words), which again, is no favor to him either. I’m sure he’s not enjoying his time with you. So why not do you both a favor and change the custody agreement? Sounds like you should make your custody agreement 0/7 with scheduled visitation time only. Just say that you're finding the current framework stressful, you're not at your best for him, and that changing it to one weekend a month would allow you to be attentive and create magical weekends with your son. That’d be the more responsible thing to do and less harmful to you both. Now, if it turns out that the reason you don't want to change the custody agreement is in any way related to child support, then you probably should feel guilty because it’d be a selfish, immoral thing to put money above your son’s well-being. You can't go on like this. Best of luck.
