Fuckin hell. A few hundred K? That's an unbelievable sum of money from where I'm sitting. Manny times how much I've been able to save over 4 years of an SWE career.
You'll be ok. Move somewhere cheaper and work in tech for a non-tech company. There's no shame in relying on your parents if you have to but as someone that doesn't have parents or anywhere near the savings you do i really think you'll be alright. Being a SWE at a non tech company really will eliminate most of your issues with the work i think.
