I had agreed to go to a party on Friday with my best friend. He has recently split up with his girlfriend and is feeling quite depressed and could do with a good night out and also we haven't seen each other in 2 months. I don't want to go to the party for 2 main reasons (a) I have had to drop out of university as I can't afford the tuition fees, so I just can't stand the idea of having to explain this to everyone all night (b) due to a above and other reasons I self harmed at Christmas and my left arm is covered in scars.
I can explain the scars to other people, for example, say I was in a RTA - but not my best friend. If he knows what I have done he will worry and I don't want that. I only have short sleeve tops suitable for a party. I have looked in second hand shops for something with long sleeves but can't find anything, and can't afford to buy new.
All I will do at the party is sit there with one drink all night and probably start to howl and cry not feel like talking to anyone and be miserable. I can't even dance as I need an operation on my leg which I can't afford (I don't live in the UK). Would it be so unreasonable to let him down and not go? Of course he is a grown man and can go on his own, but we haven't seen each other face to face for ages and he will be upset and feel let down if I don't go.
