How to get over sadness My best friends said that they wouldn't be my best friends anymore because something someone said. Even though it was a lie they decided not to believe me. I have gone through stages of extreme sadness to where if anyone would mention their name I could barley stand up. What could help me get over that sadness.

They are not even your friends if they dont believe you. Get over them. Think that they are missing a very loyal friend (i say that to myself xD) hey and i really think watching anime or reading books(funny ones) will really work.! (It worked for me) life gives lemons but you have to make a lemonade!
Find new friends and gossip in front of them (ok maybe mean but hey they deserve that for not believing ! But optional if you dont want to )
Talk with everyone you like, take new See More habits, hobbies and mahbe go cycling too.

My dad tickles me to get me to stop crying

Well first get all your crying out! then listen to music and dance around like nothing happened, next you talk to her, then is she still doesn't believe you get a new friend!

Get new friends. Be like "later losers!" and go and have fun with the new friends who will actually believe you if something like this was to happen again. Obviously, the old ones didnt deserve you. It hurts now, but later you'll be thankful for the friends who stayed with you the whole time. (If you want to continue being all depressed though, I have 1 or 2 poems posted dealing about friendship so if you wanna check them out feel free). Anyway, hope this helps.
