Terrific that you do have good support with your friends, @Dobbo xx. Lean on them. They will be wanting to help you in any way - after your surgery, it could be many things, like mowing the lawn, hanging out the laundry (as you'll not be allowed to do anything 'heavy' for a little while ......
Also consider joining the Reconstruction group - you can chat about your upcoming procedure - and may be able to see pics, similar to what you are having done. Jump on here & click 'join' ....

You will feel so relieved after it is all over - don't use Dr Google .... as a lot of info is old & won't relate to your diagnosis xx
take care & all the best
