Is what I feel toward things/people shallow and stupid?

I live for moments. I often feel nostalgic. I feel a lot and I love sharing with certain people. I create a close bound with people who share one moment with me; its romantic and appreciative. It feels like the meaning of life. Experiencing time pass with someone else, someone whom you’re learning about, its exciting. Although sometimes these moments aren’t felt mutual (I am disappointed often because people don’t view life as I do) I still value them more than anything.

This isn’t about the moments I have with people but it can be a given knowing the nature of me. On the street, subway or supermarket, rarely there are these strangers with whom I have a weird physical connection with. I feel some sort of ‘longing’ and its both sad because I can’t talk to them or start something and both nice. I’d say it makes me feel mostly bittersweet though. When I told my friend about these passionate but bittersweet encounters and feelings he said I was being very shallow and not questioning my feelings. He said “religion exists because of those feelings, your feelings are shallow, they don’t mean anything. I’m sick of you idealizing your every move as if it were something poetic.”

Am I a slave of my feelings then? Is this dumb and childish to be like this? This sensitive, passionate, emotional, romantic and poetic toward imaginative things/images?
