I don't know how bad things are in your life right now, but surely they can't be bad enough to even think about suicide. Do you have a support system ? Won't you talk to your husband ? Can you call your therapist ? If not, then call the suicide hot line if there is no one else you can turn to.
You don't want to do this !! There is always hope. Things WILL get better. There are people who love you and people you love. They are there for you. Be there for them because they need you every bit as much as you need them.
