Yaz to iud

Hey guys I am 20 years old. I am currently on yaz birth control pill. I have tried so many pills like I'm talking 8 other types. I have the worst side effects on yaz. These include crazy mood swings, depression (normally a very happy and positive person), headaches, random cramping, body pains and exhuastion. Now I'm going to get an iud next week and I'm scared. I can only find bad stories. Anyone else feel like this on yaz or the generic ? And thoughts/ positives of the iud ?
