I think I've made a huge mistake and lost my money

I think you can still use ./zcash/src/zcash-cli z_sendmany from a t_addr to a z_addr and vice versa.

See:

Correctly sending ZEC from T address to another T address

Can someone paste the correct command to send zec from T address to another T address, i really don’t want to fuck up this. $ ./src/zcash-cli z_sendmany … Thanks.

Also help is your friend:
