Birth control shot vs Spermicide

Been on it for 4 years, I’ve gained 50lbs from it, went up 4 cup sizes, I throw up so much I have to take meds to keep it down, my hair is ALWAYS falling out, my body is always aching and I haven’t had a single period since I started it. Not to mention I get dizzy, sweat non stop, and have trouble falling asleep and staying asleep now.

I have been on depo for 4 months almost. It has been a ROUGH time. From day one it’s been non stop nausea, dizziness and fatigue. I have almost no appetite ever so I keep dropping weight like crazy. Another symptom I have had since the start has been continuous tingling in my arms and legs, almost like they are about to fall asleep but don’t. My doctor said it could take some getting used to but this is almost unmanageable. When does it get to the point of feeling normal again? Not sure I can handle another couple months of this and I heard stopping the shot comes with its own set of issues because of your body trying to readjust again.

Getting off birth control and having cramps idk why I only been off for like a month or so
