One of my friends was hardly depressed , she brought a puppy for herself and she felt much more better,that 6 months she changed to a healthy fresh girl who managed everything,was responsible for it,have the passion to go out, run with it, but after 6months she lost her dog and now she is almost crazy, if she sees a dog around she starts crying sometimes shouting or calling her dog out loud...! we don't know what to do to calm her down or make her feel better!
