I've been on the decapeptyl injection for endometriosis for 2 months now, I'm due my next injection next month. Recently, I've been feeling my moods completely slipping. I'm having thoughts I would never normally have, my self esteem and confidence is completely shattered, I've never felt so low and alone before. Has anyone ever felt like this? Im assuming its side effects from the injection as nothing in my life has changed except this. I just feel like I don't know what to do anymore.
