I think you should see someone who can advise you on how to overcome
your shyness as it seems like it's getting worse and you want to nip
that in the bud before it makes you a recluse. Maybe the course
you've taken is not the right one for you? good for you for facing
your fear and taking a course like that but there's no shame in
admitting you were wrong. Is there anything else you could do?
Perhaps you could see a phsyc? You need to see some proffessional who
could help.
