We all go through these moments, I was disassociated with my own character "White" for 3 years, anyone can lose the "magic touch" at any given moment and we all have to move on to bigger and better things you know! For me, I tried a few side characters and found that none of them worked for me, so I eventually came back to this character I started with and I've never been happier.
For you, the journey will be different, but the journey will be worth every second of it, try as many characters as you want, eventually you will find something that makes you HAPPY
