It seems you already know what you want to do. You want to bring an end to this. And I pretty much agree with you, and other posters here, that you should.
I think one of the things that is causing you the most anxiety is the lack of moral support, yes? You're worried that you'll have no support from your parents and family?
If that's the case, then yeah. It's very possible, just based on what you've posted, that you might not get that support. And if you're going to go through with this, you're going to need all the support you can get to keep your spirits up and keep you on the path you've chosen.
So here are a few suggestions...I know you can't see or hear any of us, but posting here from time to time will give you a boost. Please feel free to post or PM us.
You said you live in Europe. I'm not familiar with the laws or the social/welfare programs they have set up there, so I think you should you speak to a lawyer who specializes in family/marital issues. Preferably one who is Muslim...even better would be a desi Muslim...the trifecta, of course would be a desi Muslim woman. Because not only would she be able to give you legal advice, I'm sure she'd be familiar with support groups for women who are going through similar situations. That could be a massive help to you in your situation.
Or if you have a close friend, go to her.
But please make sure you have someone you can go to. You'll need it.
Good luck. I'll pray for you.
