Because I'm miserable. I have very severe depression and I'm in a marriage that I don't want to be in. I've repressed my feelings so long out of fear of hurting others that I can't take it anymore. Therapy isn't working, medication isn't working...it's that bad. Literally the only motivation I have to keep me from driving off a tall bridge is my son. And I'm so sick of getting bashed. I'm so sick of the people closest to me telling me that it's not a big deal.
