Hi Katie J,
Welcome to the forums and thank you for sharing this here. The lovely people here will have kind words, advice and understanding for you.
We can hear there are some really big revelations you're dealing with, and adjusting to this news must be confusing, especially when you were dealing with the illness and loss of your mum during this time. If you'd like some more immediate support as you process this we’d love for you to give our counsellors a ring on 1300 22 4636, or chat to them online here.
Thank you again for your courage and strength in sharing your story here. We hope you can be as kind to yourself as you have been in sharing here, as it’s really important to look after yourself and reach out when you need to talk it through.
