What to do

Sigh...so it has been 15 years since I have had all my kids in the same town. My middle DS has been in another state and has not seen me but for a few days at a time in years. You know the deal...home for the holidays and hang with the family so you can really hid how you feel pretty easily. I've always been able to hid the way I feel...
So now...he has moved back home for a few months working virtual at his position and will be moving to another city in about 6 months or so. He has come home because the rest of us are here and he would like to reacquaint himself with his siblings and their kiddos. Fine with me.
 The problem is I can't hide my pain and brain fog and everything that comes with my fibro and migraines...etc...I even have to use a cane occasionally as I have a tendency to be unsteady on my feet and have fallen twice already without it.
It's like I am going to disappoint him once he finds out that I am not really that bustling Mom that he once knew. I'm tired...just tired. Tired of having conversations about what I can't do. 
 Oh...and how about this...I asked a 'friend' who is also retired what she does all day. She told me some of the stuff she does and then said 'but I have all my routines and don't like them disturbed so I don't like to add anyone to them'. Yep...that was so nice of her to think I wanted to join her. I'm not sure I did but it would not have hurt her to throw out an invite even if it was a pity invite. sheesh.
 Enough fussing I suppose.....thanks for reading my rant
