Am I too attached to my friends?

This comment is something I hear from my parents all the time...you are too attached to your friends, you give them too much importance...not that my parents are against it but they feel I over do it and they wish I had a better balance between my family life, my social life, and my career. I cant say that I totally disagree with their conclusions but what can I say...I am a people person...I enjoy getting to know people, I enjoy keeping people I like in my life, I enjoy long discussions, etc. I just enjoy it too much to tone it down or to attempt to rebalance my life. I like the feeling you get when you see someone whom knows you so well that he/she can predict your behaviour. I like the feeling of seeing someone and seeing a long history between us. I like remembering moments where that person really needed me or I really needed them. I was always like that but it has gotten stronger over the years and now I think my mood and happiness rely alot on the people around me which I sense can be a bit dangerous. I get quite sad when I miss people whom are there but whom I dont see as often as I like. I get quite down if I had to dissappoint someone by not showing up to their bday, their wedding, their lunch plans, their walk in the street even! Its something I realize, something I need to be careful of, but then again, if it makes me happy to email my friends abroad all the time, if it makes me happy to go running to a friend anytime he/she needs me, if it makes me happy to go down just to see a friend for one hour, if it makes me happy to travel with a bunch of people I dunno just to hang out with one friend, if all this craziness makes me happy then why should I change it? I think what made me more extreme in this regard was being in Canada and seeing how detached people were. There you had friends whom you would give maybe an hour of your time every once in a while. Maybe you would give them a call every now and then when you needed something. It was a pretty stressless way of having friends. Friends were not people who checked on you all the time as if you couldnt take care of yourself, they were not people who called you constantly for no real reason except to chat, they were not people who wasted your time but turning a quick lunch into a lunch, movie, and a walk. Their definition of a friendship was more towards people whom you had fun with once in a while when you needed a break from your responsibilities. Nothing wrong with that but it wasn't something I was used to! I enjoy sharing! I enjoy doing absolutely nothing with someone beside me! I enjoy cruising in a car with music on with a friend. I enjoy sleeping on a friend's shoulder. I enjoy having a friend discussing really emotional stuff with me. I enjoy talking about silly and irrelevant things with others. Even though all that meant friends could get nosy, could get too attached, could get too involved in your private life but I guess I prefered that kind of friendships. I know this stuff is fun for most people and that my dependence on them is what is abnormal. But I can't help it...my reason to smile is usually associated with being around people I like...and because of that I perhaps do too much in order to keep people I like close by...I dont allow them to dissappear from my life even if I havent seen them in years! I hold on to memories...I hold on to them and to people out of fear that I wont be happy without them. It is feeling I am admitting outloud for the first time...and after having done so I do feel its danger...
