I just have to echo what everyone else has been saying here. I was made fun of in middle school and High School, never really fitting in. I tried to hide parts of myself to fit in with those around me. I have found that in the last few years after moving to the other side of the country, away from everything and everyone I ever knew that I only had myself, so I've really gotten quite selfish, in a good way. You do need to focus on yourself and make sure you are happy with you. You will never be truly happy with yourself, or in any kind of happy relationship, if you are not true to yourself.
If you are feeling alone and that no one else thinks like you do. Just remember these facts.. Comic-Con attendance is over 125,000 every year, the last 3 SW Celebrations have had over 30,000 people in attendance and that's on 3 different continents. 501st and Rebel Legion membership is close to 6,000 worldwide.
