How i can help a frien of mine who are really disapointed?and shes pain hurt me

actually you can help your friend for being disappointed by inviting her to unwind such as going to a place where she can relax like go for an outing or excursion go to beaches or go for swimming...be always on her side because its much better if someone is there for her she can talk to...try to divert her attention for some curricular activities or sports...maybe you can also try to have counseling with her like say what she wants and what she feels...give her some advices to enlighten her mind that what she's going through are trials so she needs to strive hard to survive :)

I think that your being there for her will help. It might be a good idea to try and take her out shopping or dancing, or to the pub - somewhere she can be diverted from what she's going through for a day or an evening. Everyone goes through pain and bad experiences in their lives, and she'll get over it in her own time, but helping her to have fun and a laugh for a while will help her - it won't make the pain go away in the long term, but it will lift her spirits and help her to feel stronger, which in turn should help her to recover and get over whatever it is more quickly. All the best :-)
