Just confirmed with my husband, it’s for active duty too, not just veterans and it’s confidential. And it’s for families too, not just military and veterans. I’d give it a try.
You cannot force other people to get help, quit drinking or seeing therapists, it’s not in your control but you can get help for yourself and ask what they suggest about supporting loved ones in crisis, they have ideas and they are speaking from knowledge. These people receive training how to respond and I never heard anything negative.
In addition you can call about any issue, not only service trauma related. It could be anything that veteran or active duty personnel is struggling with in their life. They are there to support military and veterans AND their families in time of need, regardless what that need is.
Please seek help for yourself and your children ASAP, that’s within your control. My veteran husband sends regards.
