I mentioned this before in in my "Independence Day Fiasco" post about knowing who you are. I just kinda touched base on it since it was relative to how I was feeling and the situation that played out.
One of my favorite authors, Diana Anthills in her Sanity is Sexy book mentions that, "words or actions directed towards you by others is a reflection of their inner thoughts, insecurities and turmoil. It has nothing to do with you. You have simply triggered someone else's experience. What makes you different from them is how you choose to present yourself to the world."
You can't change how people view you. The only thing you can change and have complete power over is how you view yourself. Knowing who you are can be the strongest weapon you hold. No one will ever be able to get you down if you know who you are. They can try all they want but they will be unsuccessful in doing so each time.
Ask yourself if you really know who are? If you can completely defend yourself to anyone who comes questioning you.
If you can do so, stand firm and tall because that's an amazing quality to have and you should hold yourself to the highest esteem because it takes people several years do be okay and to be accepting of who they are.
