Is it possible that girls can be true friends to each other?

It seems impossible if you’re asking me. I’ve been struggling with friendships my whole life, losing friends one after the other. I’m the type of person that puts people and their feelings above everything but this always ends up with people taking advantage of me.

I’m not sure how that actually happens, but it’s always sudden and out of nowhere and it always hurts like hell, no matter how many times I’ve been through it. They will start by ignoring me and go out without me, then it will continue with them making fun of every single thing i do or say (i.e. give me attention but in a negative way which undervalues me), and then I will either mention it and ask why they’re doing this which leads to a fight, or I will ignore forever and live with it.

My main question is, why? Is there something I do that makes them hate me like that? I always tell the truth and not always what they want to hear because I’m honest and a true friend. I give logical advice whenever they need it as if I’m their parent and I care for them. I’m always polite, never judge and never act in a rude and disrespectful manner to them. I always end up being the animal that’s being humiliated and thrown away whenever they have nothing to get from me.

It’s not my fault that I’m a happy and humble person. I was raised to be pleased with less. The simple things make me happy and I’m not impressed by things that will certainly impress most people. I have everything I need, my family loves me and I’m healthy in every way possible. The only unhealthy part of my life is my friendship area. Why envy me like that? Why would anyone want to destroy someone just because he is happier than them?
