I agree with Minty and everyone else, nothing lasts forever and I agree form what you've said you have a lot to be unhappy about but little of that is insurmountable. this time of year is HORRIBLE for magnifying problems and emotions, s please don't do anything hasty, formulate a plan for New Year and make your life count, be selfish, do something for you that you'll enjoy and make that the start of a new you being constructed. Don't lose site of the fact that you are a special and valuable person, people do care about you, so get some help and then make a firm decision that you can and will move forward and enjoy life, you might have to be brave to do it, but it'll be so worthwhile, I promise. x
