What to expect during mastectomy recovery? Really scared and need advice

Hello,, My name is Yvonne, I will have a mastectomy on my left and a reduction/lift on the right side. My surgery is 12/9. Im really nervous about the recovery. They said it'll take 2 months to fully heal. The surgeon is also taking 2 lymphnodes out for pathology. Im hoping im cancer free. I have stage 2 Invasive Ductal Carcinoma. Just finished chemo. Has anyone been through this surgery and recovery. Please help me navigate through this. Im really scared..
