You're currently doing something you dislike. You want to stop, go take a bunch of years out studying (something you previously hated), only to return almost exactly to where you started. The implied expectation being that you'll be happier when you get there...
See I don't get it. You're already employerable, a degree won't move the needle too much, just give you a debt boat-anchor meaning you'll less flexible going forward and less able to find the thing that makes you happy.
In general I think CS degrees are great. But in your case it seems needless and like you're repeating recent mistakes, like you want to check out for another few years while you discover yourself.
I'd strongly recommend you think extremely carefully before you indebted yourself to student loans. If this plain fails, you're stuck in those jobs you hate for tens of years while you pay it off.
