well, first, for ocd, the ideal therapy to get is ERP, Exposure Response Prevention, which falls under the CBT category, but has some differences. it involves facing fears in small doses until you're no longer effected by that thing, and then facing something a little bit harder, and then a little bit harder. it is tough, but it is generally the most effective.
the social anxiety treatment that i did was part ERP and part thought challenging and changing my mindset. i did a lot of practice changing cognitive distortions.... again, the idea is to slowly expand your comfort zone. doing the treatment work is going to be uncomfortable. in ERP you purposely put yourself in the uncomfortable situation for long enough that you get used to it.
there are some self help book and apps to do ERP that you could try...
www.ocfoundation.org has some good lists i think
