Your sister went out for dinner with your aunt and didn’t tell you?
Please tell me if I am being pathetic but I’m just feeling a bit sad about it just cried at work The background to the story is that we lost our mum earlier this year, both DSis and I are late 20’s. We are a relatively close family, a few of us work together, often have family gatherings etc. Since DM passed away, DSis has been to auntys house on numerous occasions for drinks, dinner etc and neither of them have cared to tell me/invite me. We all live close together so it’s not as if it’s convenience.
Aunty has just come into work gloating how her and DSis are going out one night this week for food and drinks and how lovely it will be to catch up as they ‘haven’t seen each other for ages’… we only had a family gathering last Friday
I text DSis saying thanks for letting me know / for the invite, I have spent the morning with her and she didn’t say a word, also text DP - he just replied saying don’t know why your bothered 
Now I’m writing it down it doesn’t really seem a big deal, but I think it’s the fact that she has a mother figure in my aunt who wants to spend time with her and I don't really have anyone. Think I'm just having a bad day
