Thwarted describes something that didn't work out, like your thwarted plan to relax at home — a friend just called to ask you to help find her runaway dog.

The verb thwart describes defeating something or someone, so the adjective form, thwarted, describes something that has been defeated — or ruined — like a thwarted team that isn't going to win the championship; another team has surpassed them. If you give up on your dream of becoming a veterinarian, instead of feeling thwarted, you should put your energy into finding a different career that will be better for you.
