My sister informed me this week by WhatsApp that she is getting married. This is a marriage of convenience and I have expressed my concerns but said I will support her. She is having a tiny registry office wedding with no real guests or plans for a party. I have been invited to go but it's in 10 days time and in Poland. I called my mum to ask if she's going and whether my other sister is going and they have arranged a trip to Poland together but have not invited me. I feel really hurt and left out. I'm the eldest of 4 and my 3 sisters are half sisters and there's a 12 year age gap so I have always felt like the odd one out. One is autistic and doesn't communicate so I never see her. I call my siblings but they don't reply and I only really see them at Christmas. I had a very bad accident recently after falling off a ladder and had to have emergency surgery and only one of them asked how I was. I was rushed to addenbrooke's in Cambridge where one of my sisters lives and they didn't bother visiting or even calling or texting. They all see each other and do things together and Im always excluded. I have no children, no partner and no other family and just feel so alone in the world. Am I being silly feeling so excluded? Should I say something? I don't want to get an invite just because I've said I'm upset I'm excluded as they clearly don't want me there.
