I'm so sorry to hear about your experience. It is good that you have decided that you would benefit from seeing someone about you depression. I know it sometimes takes a good length of time via GP referral but maybe you could find some other way of talking to someone about how you feel?
I took roaccutane for three months. I had horrible side effects but my acne was so bad and I wanted to stick at it for aslong as I could. I was on 40mg daily. From day one I started having slight chest discomfort, over the weeks it gradually got worse and was apparently causing me muscularskeletal pain. I was given the option to lower the dosage at the end of my first month assessment- my pain still continued. I was orginally on a 4 month treatment plan but at the end of the three months I couldn't continue. I knew deep down it was best for me to come off with it and lead the life i used to.
My mood dramatically changed when on it. I became very emotional and quiet, I did not wanna go out. I got very annoyed at the slightest things and had violent urges, like i wanted to lash out on someone, i never did but i really felt the need to.
I hope I have helped you a little. It must be hard whenever this is causing strain on your marriage. I really hope you get the help you need soon. Where abouts in Scotland do you live? I moved to Glasgow 10 months ago
Take care, Amber x
