I love my mum and I know she loves me. However I have a very dominant elder sister who lives near my mum and who is much, much closer to my mum. She is super confident (I am shy), quite self obsessed and always needs to be centre stage. When we are together I am so left out as they always talk about friends they have in common and local problems. As she lives close my mum is always helping her and buying her stuff even though she doesn't work. I have 4 kids and work full time but she just says pity you live so far away I can't help, when we speak on the phone she always talks about my sister and kids as she sees them all the time. I feel jealous and really down about it. Am I being unreasonable?
