Admitted or claimed? Love or dependence?
Seriously consider which in both cases. Im thinking the latter for both. People who are serious about suicide aren't pushed over the edge because of a single phone call. People who are serious about suicide dont use those threats to manipulate people. Period. You need to focus on your education at this point, not a romantic relationship, and certainly not one with this level of craziness - that as much as you might want to, you can not help or have any impact on at this time/distance. You feel frustrated and like there is nothing you can do because this is a frustrating situation in which there is nothing you can do. Except save yourself. Do not lose yourself or let yourself be brought down, because that will only make it worse for both of you in the long (and short!) term. She is unwilling to help herself, and you are enabling by not forcing her to do so by cutting the ties (at least temporarily until she can get her s&^% together). If you are seriously worried about her, telephone Hamilton police and explain the situation. They will send someone (police or ambulance) to her house to check on her, which will either give her help she needs, or the wake up call to stop messing around she needs, whichever it may be. (905) 546-4925 is their non-emergency number. If shes claiming its imminent, do not hesitate and call 911, they can route an ambulance from your area to hers as long as you are very specific about the address. Just remember, you can not help her. She needs professional help and you are not a professional. You have entered a state of co-dependence which you must escape from for your own good. I think you might find some valuable information here on patterns of co-dependencyhttp://www.codependents.org/foundati...s-patterns.php

It is not selfish to worry about yourself.
