슬프다 : sad 서럽다 : sad when someone doesn’t understand you / when you feel not fair / when you don’t trust/believe you / when you didn’t do anything wrong but everyone thinks you did 섭섭하다 : sad / unsatisfied when you wised someone satisfied you with something 우울하다: depressed / 우울증 : depression **답답하다: (1) when you feel you can’t breathe well / suffocating (2) when you are in a small place so you can’t move properly (3) when someone can’t understand you even though you are doing the best to make yourself understood. (4) you think you are better to do something but someone is doing it instead of you and you just watch it 속상하다/서운하다 : it is similar to 서럽다 / 섭섭하다 but how serious is 섭섭하다/서운하다 < 속상하다/서운하다 < 서럽다. **아쉽다/아깝다 : when you almost made it but failed / When you need to finish something that you like even if you want to do it more ) I think i did the best to understand you lol This kinds of words need to be studied by making sentences by imagining a certain situation, not just memorising the meaning :) Maybe next time you better make sentences to check if you are using it properly or not. FYI, these words are based on the feelings so people may think differently from how i wrote :)
