Gosh you really do sound like my girls! Just this week the eldest one's been let down by 2 different friendship groups! But she's the nicest person I know so I have no idea what it's all about! Some people are just not as nice and if you measure their actions by your own standards....you'll probably always be disappointed. But you can't change to match them! Sorry .....mum lecture over!!
RE the BC - it's not long until your appt at the breast clinic, and I'm sure they'll put your mind at rest. You haven't worried me - the worry is always there, that's why I'm on this forum! If that pain goes, something else will take it's place someone else on my body to cause concern. It's the nature of the beast.....
