What country are you in?
In UK, there are two good websites:
Psychology today (as @somerandomguy has said), but the UK version.
Or bacp.co.uk (British association of counselling and psychotherapy).
You can search via location (although it seems most are doing it via video or phone at the moment) or various other searches.
It's how I found mine.
Check out Psychology Today's local lists. You could also consider an online service like BetterHelp.
