Deep down I am so scared of being alone and what my future holds.
I felt exactly like that too a few months ago! I think the fear keeps you from doing what is best for you and your kids. You have to try to work on that. I found that GALing really helped my self-confidence, just allowing myself to spend more time doing fun stuff, activities, time with friends, etc.
My H and his behavior toward me, very derogatory, had really destroyed my self-confidence. His texting OW, and going on dates with her made me feel really small. Time spent away from him and with supportive friends really helped me realize I was stronger and smarter than H was giving me credit for. My friends here really helped also. And I was seeing a C once a week, now 2x month. Church and my church family helped too. Maybe you could do some of this kind of stuff, too? Whatever you feel like/can fit into your schedule... Karen
