LOUIE & Spencer & all the other Newbies on this thread ~ Here's a psyche tip for you all ... "As a man thinks ... so is he!" (that goes for the ladies too) I use positive verse and quotes, etc to transform my thoughts and image of myself and it really helps. I envision myself as how I would like to be; at my goal or my best; my dream or ideal. This trick helps me to focus on a positive part of myself.
And honestly, other people are not thinking about us as much as we think (they are too busy thinking about their own lives & issues); and sometimes, they actually think good thoughts (I know I do). For those very few that don't -- who cares; they don't matter! They don't know you or your life, so they have no right to judge.
I use to feel the same as you, but now when I go out -- I pretend that I am the most beautiful person in the world! After a little practice, you will forget your old image; as it will be replaced with a new one, as you are making your changes ...
You can become what you dream ... good luck with your journey!
