I live at home and worked part time while going to school full time. For a while, I saved really well because I didn't have a life or friends. Then I got those, and my expenses went way up, but it facilitated me transitioning...
Now, on HRT and about to go full time, my money goes to medical expenses not covered by insurance, like bloodwork, therapy, certain meds, laser/electro.
I cashed out a few thousand dollars of bonds that I'd received for my college education - I should have checked which ones were high interest and kept those, but oh well - and I spent most of my saved money on full body laser before HRT. I was trying SO HARD to avoid transition. I knew what I needed to do, but... I lacked the courage. So I blew several thousand that I wish I hadn't (full body laser before HRT = largely a waste), but I had to.
My costs are in the $15-16k range right now counting black market hormones, full body laser, years of face laser, electro, legit hormones, therapy, and other uncovered costs.
I was denied a better job because of my appearance last year, but the employer I've been with for a few years now has been as good to me as it is to anyone, realistically. I've been afraid to job search and try to move on for fear of firing/discrimination/getting 'established' too much before going FT, etc.
My father has covered excessive years of community college education (read: complete ->-bleeped-<-ing waste), but before I started HRT, I was a barely functioning straight A student who didn't care about anything and couldn't learn anything.
