that is ok lol. If I can share 1 example on how to draw boundary. If someone asks for something and you have a funny hold on your stomach/gut, listen to it.
Do not right away answer, take a pause... you can either say, "maybe" or "let me get back with you on that". It is not a straight "No" because some people need practice to say this word. The above is a small step forward. ☺️ As you get comfortable and confident, you can then slowly say "No". 🫂
