over the last couple of weeks I've been noticing that when I try to speak about a specific subject OR my feelings about something/someone, there is pretty much never an answer.........

So here I am, learned myself to shut up and build up my frustrations. I don't like it AT ALL, so now I'm wondering why this always happens.
Psychology is my passion (I REALLY like observing people and reading their emotions) so maybe this is a part of why I think so much about it.
When I joke with an other psychstudent, he always gets it. So I think that the first problem has to do something with the nature of the joke (psychjokes or knowledge-jokes). But again, I'm not sure.
But now, what's up with the "I don't give a **** how u feel'-attitude of my friends? Are they all people that just wait for u to talk and then go on with their own conversation without listening or do they really simply not give a ****?
I know u can't figure this one out without knowing me, but if someone has an idea or info that would help me alot too.
Guesses, questions, all is welcome. I'm racking my brains! Whhyyyy??
It only happens with these 2 subjects. Please give me an anwser, cause I swear if this topic stays unanswered, Imma find myself some friends in the forest. Deers, wolfs, I don't even care...
Thanks already (I hope)
