Brave Search on all my personal devices, even though I’m getting worse results than up to a few months ago, so as much as it pains to admit it I sometimes use Google as a fallback (and the last time I actually used Google as my main search engine was back in 2012!). I probably should use metasearch engines more, though, but have been procrastinating learning how to effectively use them for a while now.
Aside from that, I have about a dozen sites saved with search keywords on Firefox (four of them are Wikipedia in different languages, though) that I use all the time.
Congratulations! I’m about to try to get a professional assessment, although in the particular region of Italy where I live it’s a long process for adults that involves getting appointments with two doctors before going to the “Regional Autism Centre”. That has discouraged me for quite some time but this sort of limbo sometimes is hard to bear and now I just want to know it for certain…
