Real Warriors Campaign representative and Staff Sergeant Joshua Hopper from the U.S. Marine Corps talked about some "invisible wounds" he experienced after returning home and how it affected him.

"After I came home from a tour in Iraq in 2006, I started noticing I was having problems while I was actually still deployed, and then I got home, and I probably let it go for a year to a year-and-a-half later. I just let it go too far without getting help. It nearly cost me my family, nearly cost me my career," Hopper said.

Hopper also talked about how soldiers with invisible wounds can get help.

"Whether you're in the military or not, to swallow their pride and admit 'Hey I need help with something, I can't figure it out by myself.' If you feel that something is not right, go with your gut feeling, it's probably not. Get the help early on, don't do what I did [and] wait to get the help. There is tons of resources out there. You can visit and the resources we have these days, it's unreal. We're very lucky to have them. The Vietnam veterans, the Desert Storm veterans, they didn't have the resources like we have today," Hopper said.

He explained ways veterans can connect with each other from different communities.

"For each person, it's going to be different on the type of help they need or what type of help works for them, but it ranges from counseling, meeting with other group of veterans who are experiencing the same types of problems you are, and talking it out or it could be just you going to the website. They've got a live chat function on there that's operated 24/7, where you can talk to somebody, you can even find out resources via the chat feature on the website," Hopper said.
