I can’t look at myself

Going through chemo has been so much I don’t even look like me anymore I’ve gained weight to the point I look fat I’ve lost so much weight to the point I’m really skinny any time I see myself it’s kinda surreal it doesn’t feel like me. having no hair is also just fucking with me. chemos not easy but I just want to look like me again how can I just change the way of thought and get my mind off this.
