Why not ASK your friend what he means when he says you're acting "kinda fake?" Ask him HOW you're being fake! I don't think that by being a bit quiet is being fake! Like Brackenbeard said, being a good listener is a GOOD quality -- there's nothing fake about that!
There aren't many good listeners out there anymore, from what I've found. Seems like people are always talking OVER each other these days.

No one wants to really listen to each other anymore. Geez that's maddening. LOL
Why do you feel inferior to people? You certainly are NOT.

You are JUST as good as anyone you're with! ANYONE!!! NO one is any better than you! And don't worry about P@##@# anyone off -- sometimes that can be fun. LOL It can sure make for a stimulating conversation!

I used to disagree on purpose just to get a rise out of someone. LOL That's a little mean, I know --- but I'd usually do it with someone I didn't particularly like.

(mean, I know but I'm Irish LOL )
And again like Brackenbeard said - REAL friends won't ditch you at the drop of a hat. If they do, they're not friends and you don't need those kinds of people. I too am glad you're getting out. That's great. In doing so, you're more likely to meet NEW friends which is good!
And don't be afraid to get in touch with people to make the arrangements to get together. If they can't, so what? Don't take it personally. Sometimes people are just busy -- call again another time, or wait for them to call you. But DO try to make the first call sometimes. It's good practice. Best of luck and keep us posted, ok? You're a great guy, and we'd all like to know what happens. Hugs, Lee
