I'm really glad that you have the opportunity to stay with your parents while you get your business of the ground. It might annoy you to say this, but there is something to be learned from any and every experience in life, and in this case, you might be challenged to learn patience and gratitude. It might also help if you can set up some boundaries to take care of yourself. For example, you may not want to talk about being gay with your parents at all, and I think it's fine to tell them that.
Good luck with your business and your sobriety.
