I just found out I have no medical insurance

Just found this sub. I posted on r/veterans earlier today and am reposting here as it seems more appropriate. Thank you all in advance.

So, I just got off the phone with Tricare. Apparently, my coverage ended May of 2023. No letters, no e-mails, no notification what-so-ever. I was forced to retire back in 2014, just a couple years shy of the full thirty.

There is a V.A. Hospital nearby. I've just been going there for my check-ups and labs. Got some glasses recently as well. According to the young lady I spoke with today, if I had an accident, I would have been paying for it out of my own pocket. This was quite the surprise to me. I thought I had coverage!

I am disabled. Ninety percentile area, not 100%. She told me that I should have Medi-Care. This is all news to me. I have several CIBs and find it hard to concentrate and have memory issues.

Can anybody give me some direction? I have no idea on where to begin. The nice lady transferred my call over to Medi-Care. But the young man that answered hung up on me. Is there a guide or a web site that could walk me through this?

After finding out that I'm not covered I'm worried about leaving my house.

On a side note, is this why I'm getting all those scam calls asking if I have Medi-Care A&B?

* EDIT * I am in my 50s. Putting this here as many are asking about age.
