You are grieving because you care. There's nothing wrong with that... you are grieving, because she knows what she needs to do, & won't do it.
You've done everything you could have done...this cannot control your life. You need to pick up and move on. If she wants to get better and show you how much she cares..she will go and seek treatment, and take her meds.
Some people are just selfish...and until something drastic happens, to make them realize what exactly they are doing wrong. You can lead a cat to water...but you cannot make it drink.
I would jump into a local bookstore. Educate yourself--you did *not* cause *her* problem. Do you think she is grieving right now? If she truely wanted to get better not only for herself, but for you as well- she would have done it, right?
I've done the same with my ex...eventually he will "get it". But you need to put yourself 1st- and take care of you.
I hope you are doing better-- jump into a book, join a gym, pick up a class/trade... it will get better and before you know it- everything will be back to the norm for ya!
