Ever feel like your game is going downhill?

I look back a few months ago and really think my game has gone downhill. I'm trying to look back and recall what I was doing differently than now. This is assuming I don't believe that I'm on a losing streak which I don't think. It's almost like my game has changed for the worse as a result of bad beats or thinking I learned something new that worked for someone else yet it doesn't work for me. It must be something gradual that has led to this because it took a while to realize it. Just trying to find myself again before moving on. Any thoughts or similar experiences? If so, what did you do to understand the problem?

Thanks
