I went through the same thing I’m kinda over it,but anyways if you ever need someone to talk to just ask im not sure if there’s much I can do but if you just need someone to talk to or to comfort you I’m here.
Gosh, I'm sorry to hear this. I have a son who is a teenager and I think he feels this way sometimes too, unfortunately. Are you a teen? If so, that is such a hard time in life!
Who is setting the high standards and goals for you? I try to tell my son that he needs to live for himself. Finding your own place of happiness and contentment no matter how it makes others feel is what matters.
And yes, people can be fickle. I am a very loyal person. Very. And I've been hurt by so called friends who stabbed me too. That stinks. But there are diamonds in there somewhere. Who are your loyal diamonds? And if you haven't found them, keep looking. They are there. But even our diamond friends are human and mess up. Always remember that. Cut people a bit of slack while making sure that overall, they have your back.
Anyway, more details would help. But again, sorry you are feeling badly!
