birth control
"I have had the implant for 5 months now and have not had any bleeding, acne or weight gain once. It would be an absolute dream if it didn't give me constant anxiety attacks. I am getting it removed tomorrow. But everyone is different so don't let the reviews completely put you off, but do bear in mind that any depression/anxiety/crying IS definitely caused by it. its a VERY real side effect

Avoid if you have mental health issues!"
