Haven’t been feeling right lately and I can’t explain why

I’m not usually here to complain about myself
Or be a drama queen but things have been strange lately
I send my son to summer camp in Scotland , the house is silent and feel empty . It’s not the first time this happened but it hits different now . I feel old and very emotional.
Life has been rough ( guessing it’s the same for everyone ) lately feeling tiered of all of this … circus … starting to wonder what’s the point of all of this
