Femcon FE and implanon

I am fifteen years old and I will be sixteen soon. I have tried fem con before but never really stuck with it because I kept forgetting to take the stupid pills. Well after having my period for four months straight I got back on the pill because its the only chewable one they had. (I'm terrified of swallowing pills, even if they are real small) I'm almost through my first pack and it has been THE WORST month of my life. The first few pills gave me morning sickness. I never through up because I would always eat crackers, drink water, and try to breathe it out. I still feel sick to my stomach for a little while after taking the pill. I have to eat something to get the awful taste out of my mouth.. I have gained TWENTY POUNDS in like three-four weeks. i went from wearing a size 2/3 pants to wearing a seven. Although that is not very large the drastic change is not good. Well in the past two weeks I have lost many friends because this pill makes me angry at little things. I get annoyed at little sounds and certain peoples voices. I am going into a very deep depression and have suicidal thoughts because no one wants to be around me. I am taking this pill to regulate my period and its not even working anymore! I hate this pill and everything that it is doing to my emotions and body.
