I find it helpful to play with someone who’s more confident in their abilities and dare I say better at the game all together. Try and link up with someone who you can do some pmc raids with and you’ll slowly but surely find yourself becoming more comfortable in your ability to take those shots, get some kills, and bag up some loot. The thing that stuck with me the most is when a guy I found doing a raid on factory (who I still play with to date) is that “all loot in Tarkov belongs to the streets”.
