Lost my golf swing out of sudden.

Last week I shot 79 and yesterday barely broke 100. I went to the range and could not hit a single ball without shanking. Now I’m scared to even hold a club. The only thing that keeping me from double bogeys is my putting. I followed my routine before every shots but once I get up to the ball, my brain started to chant “don’t shank it. Don’t shank it.” Boom. Shanked it.

I’m not in a good state mentally. I know how to hit the ball well but now I told everyone I paired with that I just started golf because of how embarrassing I was to even tell them I played golf my whole life. How did you guys recover from this? What did you do to get out of this phase? Is it gone forever?
