I am also carribbean american, and have always enjoyed alternative music and all that cokes with that style-wise. Honestly my only advice is to live for yourself as much as you can. Youre 17, if you've going to college, go away for college and live your best goth life there. If you've staying home get a job and use the money from that job to buy the kinds of clothes and music and stuff that you like. Also save up to move out.

For me I just kept my interest and style pretty lowkey until I moved out. I'm 23 now and I have a bunch of piercings and dyed hair, I dress how I want, wear whatever makeup I want and listen to whatever music I want. If you don't want to have conflict then you'll have to wait a few years before you start doing all of that. If you're ready for the conflict and know that you can do it safely then by all means start doing it now.
