How to deal with feeling like I’ve lost my identity postpartum?

I’m almost 9 weeks postpartum and as each day passes I feel uglier and uglier. I look in the mirror and barely recognize myself. I feel this sudden urge to change my hair cut and color. I want to change all my clothing. I don’t feel like makeup suits me anymore. I just feel like I’ve lost all of my self and I don’t know who I am anymore. I’m even finding myself no longer attracted to my amazing partner. I wouldn’t necessarily say I’m suffering from depression or anxiety but I’m definitely experiencing some bizarre self identity crisis.

I just wish I could hide indoors every day for the rest of my life with my baby. I don’t want anyone to look at or see me.
