Hey, so sorry about you results, but don't give up. You only need to improve by half a band in listening, reading and writing. Based on your Speaking score I believe you are very capable.
Visit ieltsliz.com and engvid.com and follow their tip religiously. These are incredible sites with lots of free material. They helped me get my desired scores after 2 failed attempts. So I know how you feel right now.
The only problem is it takes long and there is no guarantee. If you are willing to give it your all and can afford it, I would suggest you write again. Study for it as though it was a major exam and aim for 9s in all modules. This will give you your desired results. Last time i got 7.5 in all 4 so I know how you feel.
