Hi,

Don't feel sad and try to focus on what is required from you during the IELTS exam.
First of all, you should understand that thinking in your own language and translating into English before you talk (or write) is not a good solution, will get you nowhere.
Try to think in English, watch movies without subtitles, try to understand song lyrics, try to read a English newspaper.

Try to engage in online communities where everybody speaks English.

When you'll get that skill move to the next level: grammar.

Hope it helps :)
