Do you know how many "Floor" jokes I get. It's amazing how original some people think they are or that they'll say something never before already said. You think I haven't heard "the floor is lava" or "walk through the door, get on the floor" or "im going to go play Killing Floor" or stupid like that, well I have. Try and being a little challenging with your teases or taunts or such. Like "i love you" or something and make it seem serious, that's can be a good joke or a really bad one. I use to do this until I ran into some really bad repercussions from it and now I no longer play with people's feelings that way.
Don't you get bored of doing nothing really with your life? Like, you might have the excuse of learning a skill or attending school but it doesn't help you cope with the insignificance you are. You come here and post to people but what does that do? No one truly cares and if you thought they did and believed it you'd be talking to them in private instead of announcing it to the public.
You're not special, everyone is lonely one way or another and doing this will achieve literally nothing. You won't be helped at all. You have some maturing to do. You'll just keep doing the same stupid mistakes over and over and I'll watch hoping you learn one day but it's been months now and you haven't improved. You just use them and they use you until one of you finds another that's more compatible and will leave the other in the dust for a new one, when will you learn that.
If you really want help then go take the time to know someone on a personal level and try to bond with them. If it works out then you'll have something very special.
