What've you done, Maggie? I am out of any ideas how this should be understood and this makes my heart tear apart.
I know it can be difficult, but there is such a trick of our brain - it can be even painful as you are focused on your thoughts. Just leave them, relax and switch over to something completely different. Remember, there is nothing in our life we can't handle. Don't let your feelings take over your, because we need you to be yourself. We are always on your side.

I'm really sorry, but sometimes I feel that everyone likes their ideas of me and not the real me.

Maggie, ofcourse we all live in our own worlds, but that is not like we can't make people understand who we really are.
If you still think we are far away from understanding your nature, why don't you just open your soul, explain everythink to us?
That is what I want most of all, so everybody became a person, and not play games being someone else, hiding the real thoughts and desires.
Don't afraid to be 100% true yourself, being real is the only way to make the others see you real. =)

I'm afraid that noone will like the real "me".

Just try it! There is no point in thinking how it can turn out, bacause you will never now.
