Why some ppl are so FAKE!

Recently, I am feeling people are very fake. The reason I say that is because i realized a lot people I know they just used me as their "antidepressant" to get over their depression.

They talk to me when they are sad, as soon as they find other friends or other things to do, you can't find them anymore. I want being there for my friends, and i want the same in return, because I was always consistent with my friends whether they were happy or sad.

But not all people are sincere, a lot ppl i know have the tendency to use me as their temporary friend and I hate being used! Maybe they didn't do that intensionally, maybe they didn't think it would be a big deal, since I am always a very easy-going person, maybe they just thought I wouldn't get angry anyway. That is such wrong assumption! I can get angry too, really angry...........and disappointed.

Why some ppl so phony? They just suck all your moral support and positive energy out of you and once they get better, they left. When you are the one feeling lonly, you won't find them anywhere anymore...
