I think I can reassure you on that point. Your fellow citizens will not spit a you, snub you at social gatherings or call you a "Baby Killer". You'll be more than welcome especially by your fellow Veterans. There are many more support systems today & not quite as many clueless clods
I got out in '72 & ended up leaving the country after 3 months & bumming around the world for 2 years
Only one word of advice, get registered & square with the nearest V.A. Hospital & document all "Service Connected" disabilities, injuries etc. & double check EVERYTHING they tell you.
The sooner you register after discharge, the better. I think you have to check in every year or so to stay registered.
Not to be a wet blanket, but those occasional, minor coughs, aches & pains ain't gonna get any better over the decades Please don't hesitate to contact me via P.M. with any questions you may have
Best wishes & many thanks
