Hello Prefabsprout
I am exactly the same way! My ex husband used to call me a martyr when we were married. He used it in a negative way, and Its very difficult to stop negative self talk. But we have to keep working on it. Physically be aware of negative thoughts and halt them immediately and find something positive to replace that thought with. It's extremely hard because it has become so automatic to think and say what's wrong instead of what's right!!
Let's practice being kind to ourselves and maybe turn it into a good habit.
You are as valuable and worthy as anyone and everyone else on the planet!
