You aren't a coward.
As you've described in another post, you are courageously living with a very difficult illness. I admire your strength.
Sometimes, living with, struggling with, our illness(es) is overwhelming. During those times, other issues must wait.
I am very sorry your husband emotionally abuses you and does not add to your sense of worthiness. You deserve better.
Do you need help with your depression?
Do you see a therapist and/or a pdoc?
It's a good sign you are reaching out!
Please continue to reach out here and in real life.
You deserve a good life. You are worth it.
