help me /adv/, for I am on the verge of tears

Some time ago I dedicated myself to something. You might call it a skill. I enjoyed it very much and kept training. 2 and a half years have passed and, after spending a considerable amount of money, I realized I fucking suck at it.

I suck at it bad.
I still like it, but I suck so much my hopes have been drained.

does this happen often when you dedicate yourself to something? Or is it abnormal? My motivation has gone down the drain and I feel fucking depressed because I invested a lot of time and money on it. Plus, as I still like it, it sucks to say goodbye.

I wish I had a real passion, something for which my motivation wouldn't evaporate this quickly...
