I have no real understanding of the visa situation for the States (although my perception is that it's a long way from straight forward), but just out of interest, have you looked at other options? If you're looking for English speaking, Canada, New Zealand and Australia are obvious alternatives you could explore, depending on precisely what you were looking for.
My family and I emigrated from the UK to Australia a little over a year ago so I can speak to that one, and personally, I don't regret it for a second. There are of course things that I occasionally miss, mostly friends and the footy, but aside from that, the lifestyle here in comparison to what we had in England doesn't compare in my eyes. In case you were interested in taking a look at Australia (purely because that's the one that I know the most about), the best way of getting in permanently is via what they define as a skilled occupation (unless you have family there already, or a shit tonne of money). The list for that changes regularly but you can find it here:
https://immi.homeaffairs.gov.au/visas/working-in-australia/skill-occupation-listI know you said you worked in IT, and as it happens, I got my visa via previous experience in IT Support (even though at the time of applying I'd moved away from that role and had no intention of going back to it). The other thing I did was use an emigration agent (specifically, The Emigration Group, albeit I think they've ceased operations in the UK following Covid doing them in pretty badly). One benefit to using an agent was that, once I had a file open with them, they monitored the skills list for me on an ongoing basis and contacted me whenever I had a live option to see if it was one I'd like to pursue. They also, for a while, were looking for options in New Zealand as well as Australia, simultaneously, keeping options open. Might be worth having a chat with a similar company to see what options you might have in a bit more detail.
Anyway, just thought I'd float some obvious other options, in case you hadn't considered them yet and were potentially interested. Happy to answer any questions if the Aussie route is something you might look at.
That all said, there is a lot of truth in this as well:
In short, don't rush in to something drastic and take care of yourself.
No harm in having an obligation free chat about options, and while you do that you have plenty of time to have a big think about what you want to actually do. For me, I'd spent a decade trying to find a way out here, so I was dead set on it for a long time, and had lived here twice previously, so knew it was something I wanted to do.
If this is your dream, though, it's never too late to chase it
