Star Trek (Mostly TOS) means a lot to me too, so I understand how you feel. I had some difficult times growing up. My mother used drugs and things were unpredictable and rough at times. I had real friends, but the characters felt just as close. Roddenberry's philosophy appealed to me and actually moved me closer to accepting my own humanist beliefs. I thank him very much for that. My first serious girlfriend and I bonded over watching the shows.
So yeah, Star Trek has had a pretty big impact on me. I mostly just watch it for pure entertainment now, but the characters still feel like old friends.
