Ability Descending/Declining

And Here appears what I'm afraid of!. My ability began to takes/has taken a step back(wards)/backward step. The high degree of enthusiasm at the beginning starts to vanishes. I need to continue my progress in improving my English (as I wish) this year. What happened to me ? :( !. Does anyone know a way to encourage me again?.

It happens to many of us.  I haven't been practising Italian for a month, and now I feel as though I am 'back at square one' - the beginning.  We just have to pull ourselves up again, and recover the lost ground.  It is usually easier the second time around, but still frustrating to have to do it.
