Hi taraz. I think you have an excuse if you have been posting 5 times a day fro 2 years to struggle some days. I have been on here a while now and haven't really had any blockages of thought yet. Those days will come I am sure but if you look around there is always something.
Don't be so sure. There might be moments, rarely days. At least that is what I find because the more I write, the more I can and as I find authors that have interesting thoughts, I find I springboard off them and have an endless amount of topics but, a finite amount of time.
