I hope your next week get's better!! Let's see if I can say anything that might make you feel better
If your boyfriend dumped you for that other girl and was a jerk, then bye-bye birdie. It's his loss not your's, you deserve someone better then that, you'll find someone that you like and will treat you right. I really hate to hear that about your friend, maybe you could talk to your friend and see if they will let you help?? And as for your dad, if you don't mind me asking, why does he hate the horses? I'm not sure how old you are, so sorry if this sounds too young!!, but maybe if you show him how much you love the horses and show him how responsable you can be with them and with other things, he may change his mind. If it's money, maybe you could help out some if your not already doing so?? Try to talk to him if you can, maybe you two can compramise? I REALLY hope that your next week get's better!!! Like Meggymoo said- Keep your chin up!
