So much of this thread had been taken up by 'eating out alone' and its been right up the OP's very familiar street because its meant she's not had to think about of any of the posts offering encouragement.
She didn't want to do this trip with anyone but the person she's just broken up with and I think she posted so that when we offered encouragement she could see all what she was going to miss and say to herself - that bastard, look what they're making me miss. I suspect she really did want this trip to go down in her history as 'the trip of a lifetime I missed because of that *%$@'
As for the mention of the Philosopher and the OP's willingness to take refuge in what they said, again it was an easy way out, and it's obvious what her mindset is regarding those who can go off alone.
Perhaps OP you could think of this
Happiness is a continuation of happenings which are not resisted (Deepak Chopra)
Being alone is finding the secret of your true self (Ralph Smart)
Attitude is a little thing that makes a big difference (Winston Churchill)
I like the challenge of trying different things and wondering whether it’s going to work or whether I’m going to fall flat on my face. (Johnny Depp)
If you aren’t in over your head, how do you know how tall you are? (T.S. Eliot)
Never let eating alone in a restaurant be an excuse for not doing something. (Some strange posters at Mumsnet)
You've been very defeatist on this thread, you've also been quite cutting, but you've had a break up and its not inclined to bring out the best in us so here's to some peace of heart and mind for you soon.
