I love to look at myself in the mirror but lately ive been very self conscious about myself, do you know about some ways to help with it? 
Well I suffer from it too.  it is a high sense of self-awareness.
Indeed some people are more aware of how they look in public like how I do, Is there therapy for this type of feeling? 
Yeah it is recommeded you see a doctor.  It is a preoccupation with oneself, as opposed to the philosophical state of self-awareness,
Oh interesting, Do a lot of people have this problem? How do people usually handle it on their own? 
It can be tough and everyone is different. An unpleasant feeling of self-consciousness may occur when one realizes that one is being watched 
Sounds scary, I usually look at myself in the mirror and really get scared that I wont look my best and knowing that everyone is watching what I am wearing.
Self-consciousness
Self-consciousness is a heightened sense of self-awareness. It is a preoccupation with oneself, as opposed to the philosophical state of self-awareness, which is the awareness that one exists as an individual being, though the two terms are commonly used interchangeably or synonymously. An unpleasant feeling of self-consciousness may occur when one realizes that one is being watched or observed, the feeling that "everyone is looking" at oneself. Some people are habitually more self-conscious than others. Unpleasant
You don't know how you look on stage, but if what you're doing reads clearly it means you have to try to be quite honest, because otherwise it shows. You have to be very aware of how you work with yourself - it all comes from what you feel at that moment. When I do James, for instance, I actually say the lines to myself as I'm doing the mime. Not always, but... you have to have the overall feeling at that moment, in that scene;
