Person hit by train (March 2024) Clapham Junction

I witnessed a man get hit by a train 20/03/2024 at Clapham Junction platform 5. It's coming up to a year and I'm still struggling to come to terms with it (on and off) I wanted to reach out and see if anyone else who was at the same incident is here? How're you doing? Or anyone that has been through it - how do you cope? TIA
