You don't have writers block

Cause as you said your not writing...but making music

But i've just gone through exactly what your going through. I tried a lot of what people said i.e ^ TI's post lol. And none of it worked! lol, i did take a lot of time off. try just taking a step back from music all together. All i can say is i didn't open FL up as much, i didn't try and force music, and i spent more time out of the house and after about a month or so i've made a couple tracks within a week so im starting to get back into the groove of things now

But honestly i can think of one thing i did that 'cured' this problem...I think its just time imho
