To quote one of my children, now 36 years old. "Life is hard--and that's alright. But it should not be miserable."
Do not stay. You do not want a miserable life.
The life you have described can't rise above miserable even if all the WTBTS literature and songs teach you to say otherwise.
You can't rewind, unwind your experience and perceptions of life as a JW. Your desire to serve God will have to contort into a distortion of the gospel to fit into JW life. Don't let yourself get bent that way. Don't marry "in the Truth". Get with a life companion with whom you can share your life honestly.
I don't try to run other people's lives but I want to be clear in this instance: this is spiritual warfare and the WTS will crush your spirit. Leave the religion and find your life.
