PLEASE HELP - Why doesnt My Mum love me and how can i learn to accept it ?

This has got to be one of the saddest stories ive read. There was a time when me and my mother were on bad terms for a long time. She would never call me. Unless she heard something about me or had something to b*tch about. But maybe if you can get her to possibly sit down and have a one on one conversation face to face, maybe at a coffee shop or a resteraunt. Or better yet maybe write her a letter, and cover absolutly everything. Your feelings, your childhood, how she made you feel, the difference between you and your other siblings, etc. If this doesnt work, im sorry to say but she is most deffinatly in the wrong, and she will realize it the hard way. But for this much pain in your life of being beytrayed and heartbroken because of the behavior and ult your mother has put you through all of these years, makes you a stronger person. I hope for the best for you. Good luck. Stay strong and keep your head up!
