I feel so deflated, I've been trying to become a mother but I keep failing. I think I won't be a good mother even if I do get pregnant.
Don't judge yourself so harshly. Why do you think you wouldn't make a good mother?
If I can't get pregnant, it feels like a sign that I shouldn't have children.
Its only natural to begin to feel discouraged by a situation like this. However, don't allow it to make you feel that everything in the future is going to be negative. Dont let the ill thoughts ruminate too long, and realize that things get better with time.
I don't know if I can put my feelings of worthlessness behind me.
We all struggle with things we want to achieve. I think you should join a support group for other people that are in your same situation. Talking to others that are experiencing the same struggle could really help you.
