It’s a shame you have not had a good experience of studying and not made friends and don’t feel like going . I did not want to go to mine but I did and glad I did but don’t have any photos. I do have some brochures though. Your name will be in them etc. I would go as it is an achievement that you graduated, you get to wear a robe and hat and it is a celebratory event and takes you out of the day to day. There may be different speakers etc. I’m sure your mum is proud and wishes to celebrate. I did a post grad and went to that remember it more and have a photo so pleased about that. I would definitely go. It will be a fun, once in a lifetime event. Congratulations!
