Mental suffering. She lie down to sleep!

There's a friend of mine who opened up to me one day about what she was hiding from years. She complained of something very unusual. She said when ever she hears someone talking negative about anything or anyone she feels a severe pain in her self. When someone talks about something that's a lie and if she knows its lie she feels an unbearable pain for not able to correct them. Even if its happening on TV or news channel and someone in her family talks negative of it, she feels broken. Then after, she loved someone but her family rejected the boy saying untrue things about him when she knew the truth. With this the problem with her became severe. She suffered insomnia then hypersomnia and now migraine which is sooo severe. She holds her self back for the whole and waits counting every minute for the clock to strike 9pm so she can close lights and cry like hell. Whatever negativity and ill untrue things she's heard the whole day starts flashing in front of her when she lie down to sleep
