Going Off Depo Shot

I had been on the depo shot for 3 years. I decided to get off of it due to the bone loss issue. While on the shot I experienced every symptom mentioned with exception of weight gain. I probably would have gained weight but due to the depression anxiety and an on again off again relationship with my boyfriend, I did not eat as much. I dont really have an appetite when I am upset or depressed. My biggest problem now is, I am having no period having been off of it for 4 months. I have been reading that that is normal.. My breast are so so tender that they hurt when I lay on my stomach. They seemed to have enlarged as well... I would like to know why this happens and if it is a common thing when coming off the shot.. I would appreciate anyones input on this. I thought maybe I was crazy because I was so moody too while on it, but I can see after reading that Im not the only one.. I cannot wait to be normal again . Thanks and God Bless
