I agree that you need to talk to someone that can help you sort all this out and make you feel better about yourself.
We all have secrets we carry. But after all you have been through, I see a VERY brave lady! And what really impresses me is the fact that you want to save your M after all the things men did to you. It just proves how strong you really are!
Don't feel guilty about anything in your past, it is the present and the future that counts. I see someone who is willing to do what it takes to get past all the pain.
This doesn't in any way change how I feel about you! And I've chatted with you many times and have read what a wonderful mother you are!
There is no doubt in my mind you will be able to work through this! And know we are all here supporting you in any way we can!
