It's good that you're thinking of education, to me it's the only way forward as I can feel my body slowly break down, no matter what I do.
Have you completed University Preparation, aka Highschool Upgrading? You can take them for free at MacEwan (Alberta College campus) through AlbertaWorks if the fascists haven't cut it. I highly suggest applying for full time courses, which pays your rent as well (fascist disclaimer). You will likely have to do so if your highschool transcripts are more than five years old or aren't "competitive".
UoA is competitive so be prepared to not be accepted, which means applying to other universities. I suggest the University of Victoria, in BC. Maybe do your first year courses there, then see about transferring to UoA. Makes it a lot easier to get in that way. Suggest not staying tho, UVic is becoming... corporate.
There is also a large queer community in Victoria, especially UVic. I suspect the gayness is a bit muted in Alberta due to the political climate.
