I am very well aware of the suicidal feelings with this condition. It's mindboggling how something so "small" can have such a big impact in your life. It penetrates so deeply into your emotional capacity. I have been suffering from this for 20 years now, and can attest to the periods of severe Depression that I have gone through.
I am glad that Prozac is helping, however much it can. I have really tried to ignore it as much as possible and try to live my life, even if it is secluded - online classes, running on mountains, etc. Things that will expose you to healthy environments and keep you progressing in life and away from very crowded places which can help not constantly having to worry about the lips. At least this path has helped me a lot.
