Lottie, I just posted on your other thread in the pregnancy section - thanks max for pointing me here!
Please, please don't run away hun. It really won't fix anything. The best thing I can suggest is to take some time out for yourself - you don't have to tell anyone today if you don't want to. Keep it to yourself, mul things over, think about what YOU want and what is best for you, then go and see your GP tomorrow. They will be able to offer you support whatever you choose to do.
One thing I can promise is that it won't be as bad as you think it will be, nothing ever is. And don't put yourself down, you're not foolish. You do need to start taking responsibility though sweetie, and that means facing the issue head on - go and see your GP, don't run away xx
