Hey @Cruiser. Everyone above has given you brilliant advice. I want to add my voice to the others who've suggested having someone with you for the first 24 hours. I'd suggest 48 hours would be optimum.
Now is the time to put yourself first. Seriously. If you have to have someone in your home, your sanctuary, who would that be? Go with your gut. Don't go to someone else's house. Tell them if you're asked that you've been advised not to. You need to be in your own space, physically and emotionally.
Remember that good friends and family seldom offer to help without meaning it. If it was your good friend or family member, you'd want to help them. Now is the time to accept help; it is one of the more humbling lessons that BC teaches us. If your mum wants to look after you and you're happy to let her, don't worry about the distance. I'd travel the globe to help my babies!
I couldn't lift my arm very high for the first few days after my lumpectomy and sentinel node biopsy. My husband had to help shower me. It only took a few days to get back to about 90%, but you are definitely restricted at first.
I'm sorry you've joined us, but I hope you'll find it as welcoming and supportive as I have. Big hug, K xox
PS I have had 8 gajillion meltdowns, including one last night. It's pretty normal so take it easy on yourself. Better for your mental health to let it out than hold it in.
