I Am Not Alone, But I Still Feel Alone

I forgot to make a post for this last time when I planned to, a while ago I went to six flags with the family and thing is it was fun...but I felt alone you know, I remember getting on the hot air ballon ride (Not real hot air balloons, it was just I ride that took you up and rode you in circles) and I remembering feeling both a type of serenity and lonliness in a way. I mean sure I was with family but like I though "I wish I was here with someone who understood me/that was special in a way"...I mean my family knows me and stuff but like they don't really understand me....
