I know exactly how you feel, I've had so many lying, manipulative and frankly insane people around me.. Eventually I had enough and decided I wasn't going to put up with it anymore. And neither should you! Allow yourself to feel whatever it is you are feeling. Feelings are good and it's through them we heal. Then go find better friends, you deserve better. You deserve to be around people that love you, respect you and care about you. Life's to short and precious to settle for anything less! And right now, honestly yes I am really lonely after deciding to drop all those "so called friends" so I know how you feel but I know eventually better people will come into my life. And same thing will happen to you! Rise above them and look for something better. I wish you all the best.
