Boundaries

so we talked about boundaries yesterday, very interesting. Boundaries are invisble borders in which you have in a physical, mental, and emotional way. I never knew that i had things called "boundaries" because it was just like whatever. It made me think of those times when my boundaries were passed. (Ex : people copying my homework, having my alone time violated, and just never saying no to things i didn't want to say.) It made me realize by doing that, I was not taking control of my life and my happiness. I was just making it worse for myself. I was AFRAID of people's reaction whenever i say no so i just let them do it anyway knowing that i will feel horrible about not speaking up about it afterwards. Why do I do that? If i tell them, will it such make me to be a worse person to them because I didn't do what they ask. I would like to help someone out of love and not just because people tell me to and i do it bitterly and feeling guilty. At the same time, i wish people would respect my boundaries and I learn to respect other people's for the time in the future.
