A shy extrovert?? Really?

[me]

I was told today I was a "shy extrovert." Whatever that means lol

I love being around other people, love being around friends, love meeting new people, going out etc, I don't mind alone time every now and then, but I am most happiest around other people. Even if I am not really socialising as such, not really talking a lot. I am shy around people I don't know (well at first anyway). Even with some friends of mine I don't talk much.

But I was told because I enjoy being around other people BUT I am shy, I am a shy extrovert. I always thought I was introverted but apparently (from what I've been told) being extroverted or introverted has nothing or very little to do with being shy or outgoing, but rather where you get your energy from. Eg an introvert gets his/her energy from being alone wheras an extrovert gets his/her energy from being around other people. I NEED to socialise all the time. Even if I am home alone I am constantly socialising, either on the phone or social media. I go mad if I don't socialise on a daily basis, even though I don't talk a lot at times.

I hope this makes sense.
I am the first to arrive at a party and always the last to leave.

If I had the choice to stay home on Saturday night for example and watch tv, basically 'do nothing' OR go to a friends (or have a friend over) and do the exact same thing, I'd choose the latter, even if I am really tired and couldn't be bothered actually going anywhere, I'd choose this because I need other people around. I need to socialise.
A lot of the time when meeting new people, I DO talk but not as often at first. I like to observe and take everything in first and THEN (after a while, when I am comfortable etc) then I don't shut up lol. But many people when first meeting me think I am snobbish or standoffish, but I am really not. Maybe it's body language. I don't know. But I do enjoy being around other people, whether that's a small group or a larger group, though the smaller groups I feel more confortable. If I am alone for any more than a day I get kind of depressed/sad so need to be around others, even if I am not physically around people, like I mentioned before even if it's just through social media (Facebook for example). I have a friend who talks and talks. She'll talk to anyone about anything, doesn't seem shy at all. BUT she prefers being alone most of the time. She does like getting out and about with friends etc, but yeah...she prefers alone time to unwind and all that. I NEED s
