It truly is, when I was younger a few friends and myself all signed up for the Marines to go over and help our soldiers, it was a sad time when I didn't make it through due to a heart condition my parents never told me about and they did. One of my friends came back without his legs and I avoided him because I felt so ashamed of not being there as well but he got a lot of help from the VA and the community but I didn't know him that well after he came back. Point being, it does really take getting to know the ones facing those invisible struggles to realize just how much they're going through and it really is up us to show our gratitude and humanity to try and be there for them however we can, however they'll accept us.
