@annanyc,
Killing yourself over that?
Yes we all have problems but you do have a degree low GPA or not and I assume your health and you are better off then 99.9 percent of the world population.
Let's see off the top of my head there are programs for anyone with a four years degree to become a teacher for example and that is just a suggestion you might wish to look into.
Lot of others possibilities if you look outside the box.
Surely your problems does not at age 27 called for the ending of your live in my opinion and I am sure in most opinions.
Things will get better and we all are here for such a short time as it is it is kind of crazy to end a life early over the problem you had stated.
Get some counseling and medical care for your depression and begin to view the world as the wonderful place it is even with problems.
