I agree that the haircut was the right start.

I think you may just need to get used to you with curly hair. Shorter curly hair for the time being. I also came from a lifetime of waist-length, relaxed, straight hair and it's an adjustment...it's an adjustment to see yourself differently especially when you liked your look before.

Give yourself the time, keep doing the healthy things for your hair...learn its properties (texture/thickness and porosity) and the rest will come.
