What's a safe and fun messaging/chat site, that I can use to replace Facebook?

Ok, so I'm getting really sick of Facebook and also upset about almost everything I see on it. I don't have many FB "friends" (and people are also constantly unfriending me, or not even accepting my friend requests, even when we've actually talked in real life) or get many "likes" (most I've gotten on a profile picture is 14, when the popular girls will get 200+ :/), and I always to compare myself to others on it, and it especially hurts when I see people, who I thought were less popular than me, getting more "likes" than me. When I see the people who I'd actually consider friends, doing stuff without me, I feel left out, when I see that my crush has liked another girl's photo (not that he's ever "liked" mine though), or even when he's just online at the same time as one of these girl, I get extremely jealous, and when I just see a really pretty girl in general, I feel really bad about myself. Plus I get lots of adds by random guys (no racist, but usually from India or somewhere in the Middle East), which I accept to have more friends, so I can reach a "normal amount" (300-400, as opposed to 162 :/), and they'll always start creepy conversations with me. I also spend too much time on it. Although I got straight A's in almost every subject last year, I will be doing much harder subjects this year, so don't want to waste my time looking at people's photos and getting pissed off.

However, even though I just listed heaps of negative things about it, I really do like the chat/messaging part of it, when it comes to talking to friends and arranging catch ups and things like that. I have a group chat with me and my 3 other best friends, where we talk pretty much every day (as well as in one-on-one conversations), and I also have some good friends who don't go to the same school as me.

I'd had my Facebook account deactivated before, and texting/calling was a really ineffective way to talk and arrange things :/. Also, I have kik, but one of my best friends (who is part of the 'group chat'), doesn't want to get it, because she thinks it's unsafe, and I don't want to pressure her to do anything.

So to sum up my question, is there another site or app, with a messaging/chat system similar to Facebook (also I've already got Facebook massager, but I want something completely non Facebook), which would be safe and enjoyable, which I could convince about 10 friends who I actually talk to on Facebook, to get it, which they would enjoy as much as Facebook, or if not, how can I deal with my negative thoughts about Facebook, and all the negative emotions it brings upon me???

All of these involve signing up, but they'll be safe and private. TheOtaku.com has a chat room which you can make private. Or you can join the community chat but there's usually not a lot of people on it at the same time. Or you can sign up for skype. Not only does it include video messaging but you can also send regular messages at the bottom of your screen.

(And I think 14 likes is a lot of a picture. But "likes" doesn't always equal beauty. I usually get 3-4 on a pic. Just a piece of advice, if it bothers you how many likes the "pretty" girls get, just unfriend them. And the number of friends you have shouldn't matter either. I'd unfriend all those creepy guys too. Keep the ones that matter close to you. Those are the real friends.)
