Sorry to hear that @daan. Loss is never easy and while you will always feel it. At least you know that he had a big part in your life and that you continue to show his legacy as you grow older. The best thing you can do is to live a life he would be proud of and stick close to your brother in these tough times.
Ar dheis Dé go raibh a anam.
That's exactly what me and my brother will try to do, we'll stick together in these rough times for sure. Thank you for leaving a very helpful and supportive comment, appreciate it very much!
