Looking for advice

I Apologise if this isn’t the right place in Reddit, but I figure that military or veterans would maybe understand my situation. So I’m in my early 30s and I got out of the military in 2019. I had a pretty rough transition with addiction and mental health and I decided to use vocational rehab rehabilitation when I left the military. I got my degree and I’m 100% permanent in total. the housing stipend I put into a high-yield savings account. I lived in my car for the entire time that I’ve left the military and lived off my VA disability. I currently have over 30K in a high-yield savings account once I have reaches that much, I decided that for my overall well-being I wanted to live overseas. currently I’m in Southeast Asia. Intuitively as I am not a financial expert and no one has really taught or guided me. I put $3000 into my regular bank savings account, 500, I contribute to a mutual fund and then 500 I contribute to my Vanguard ETF and two others. (200 VOO, 100 in each of the other ETF) my checking account, I keep it around 1300 as the cost of living where I’m at is very cheap. The savings account that I have with my bank is usually for wire transfers to my landlord as I pay one year in advance for rent, which is about $3000. Just wanted to see if I’m doing things right? Any way to optimize my decisions? I cannot open a Roth IRA because my VA income is non-taxable. I’m looking for a remote work as an English teacher and once I get that job I plan on using that money for investments as well…. So any pointers would be great. I’m just trying to secure myself for my older self and start my life up again. Thank you for reading if you made it this far. I understand I started late and not in my 20s but any help would be appreciated.
