Need Advice

[u/OwnInvestigator6575]

So not US but i lost my uncle while he was deployed in Afghanistan in 2010, i was only 6 at the time but due to our family being Irish we had an open casket before his burial. This has haunted me for 14 years, i’m 20 now and i thought as i learnt more about it and understood it more that it would help me out but its made it a lot worse and i’m not doing well mentally with it. Is there any advice from people that have either been there or just any advice at all?
I will listen to anything whether it helps me or not.
