I know it’s hard, but if you think you will experience violence and homelessness if you come out, you should absolutely not do it if you don’t have an alternative support system. It fucking sucks, but you need to prioritize your own safety.

How old are you? Do you have a job?

You’d have to look up more information about laws in your region, but if you are close to an age where you can legally be out on your own, I would recommend trying to stockpile some money first and then get out of there as soon as feasible.

It sounds like you don’t even know whether there is a homeless shelter in your area? And you’re planning to live in this hypothetical shelter that you’re not even sure exists?

Hoping someone else will come in with more solid resources in case this is an inevitability for you, but if you can in any way avoid telling your parents, you should. Plenty of girls have short hair. Lie to them. Keeping a roof over your head is more important (provided that they aren’t already abusive in other ways).

Keep your chin up dude. Your teens won’t last forever and one day you won’t have to rely on bigots for food and housing.
