Birth Control

I would like some opinions on Birth Control.  I have a 4 year old and a 7 month old. I've had the hardest time finding a birth control that I do okay with. I didn't do well with the Nuvaring or pills. The pills because I have very bad anxiety from some past experiences and pills is something I've never been good at, the thought of it makes me very anxious. With the nexplanon, I bled for 7 months straight after my first baby. I'm on Depo now and I've gained 40lbs on the depo alone not to mention I've lost most of my hair. Now, I'd like to try the IUD but when I went with my sister, she fainted and that scared the s*** out of me. I'm out of options aren't I!?
