How do I (F40) accept that i’m never going to be anyone’s favorite in life and that I’m never going to be married?

FIRST OFF PLEASE DON’T MOCK ME OR MAKE FUN of ME IN THE COMMENTS SECTION. PLEASE DON’T RECOMMEND THERAPY. MY HEALTH INSURANCE ONLY COVERS A FEW SESSIONS AND MY LIFE IS ALREADY FILLED WITH CONSTANT MEDICAL APPOINTMENTS. I’m a 40 year old female and i’ve been disabled since I was 14. Before I was disabled, I was never the favorite grandchild or niece. I was never asked to be a flower girl in weddings. In adultood, I’ve never bee one of the the friends who gets asked to be in a wedding parties or other milestone events for friends. Dating has been struggle at times because of my disability and I wish I could at least be married and have someone to spend my life with.

I know i’m not anyone’s favorite person. i never get asked to do readings or have roles in the funerals for deceased relatives especially those who I loved.

Please don’t give me advice on getting a pet. I have pets that I love, but they’re not people and I crave deep human connections that I see other people having with friends and loved ones.

I know I will probably never be anyone’s favorite in life and please don’t tell me to be my own favorite person. It doesn’t work that way. I just wish that I knew that I matter a lot to someone, but I also want to try and accept that i’m never anyone’s favorite.

TL: DR how i accept that i’m never anyone’s favorite in life and will probably never get married
