Arm BC implant! Questions!

Ive been on the arm implant BC for about 2 years now and im about to get it out in September. Since ive been on this BC i had some big changes and wondering if i wasnt the only one.

In 2014 i weighed almost 140lbs and im only 5"2. Now in 2016 i weigh 103lbs. Ive lost alot of weight were my family members think im a junkie, i cry almost 25 days out of the month and i also am a monster on top of that. And over this 2 year period ive been in the hospital for panic attacks due to the mood swings i developed too. My iron level is so low, i bruise like a peach l,My period is a mess it comes and stays for almost a week and a half then it will be gone for the next month. Im 20 years old and my body feels like 70 year old with the back and joint pain i have. I used to be a up beat happy girl and i really feel like this BC changed my life in a bad way. There is my story am i alone in this?? Alllsoooooo My sister is looking for a BC and she want what i have, i told her NO! what do you think?
