Under 35 double mastectomy

Hey everyone,
I’ve been reading these forums since I was diagnosed a couple of months ago and have found them so reassuring to know I’m not alone so thought I’d see if there was anyone who had been through a double mastectomy and lymph node clearance? What was the recovery like? Did you need any further treatment? I can’t have radiotherapy because of previous cancers and genetics. Also looks like I’ll potentially need chemotherapy depending on what they find in the lymph nodes and definitely tamoxifen for 5-10 years. What have peoples’ experiences been being young and having chemo and/or on tamoxifen?
I’m currently 29 and have been through cancer twice before but this feels like a whole new ball game.
