And welcome to the depression forum. We aren't allowed to discuss suicide on this forum, so I can't reply about that. But I can about the other things.
Don't let your parents dictate your life. Don't rush into marriage or make him choose between you and his parents. He will only become angry about that eventually. Let the relationship go as it will. Get back on your medications. It does sound like you may need them. If you weren't depressed, I don't think you would see the things the way that you are. But most of all, let the relationship take it's course. Don't try to rush it into a life changing decision.
Stay away from alcohol. It only makes you more depressed. Why do you think that you are looking in the wrong direction for answers when the right decisions are right in front of you? I think it is the depression doing the thinking for you. I think you know what to do. And don't stop the meditation and yoga. They are both good for you. I am glad to hear that you are doing them.
Take life one day at a time. Enjoy your relationship whatever stage it may be at. Don't take it for granted by wanting to get married. Discuss it with your boyfriend and see what he wants. Then make a compromise. If you force him into this decision he may have regrets down the road. You don't want that. You want a stable relationship. You want him to be happy too. I know you can do this. Do keep up the meditation, it is so good for peace of mind. And please see a counselor. Let them know the extent of how you are feeling.
