Single people, how to not feel sadly alerted after seeing happy couples?

Long story short !

I understand that what meant for you it will found you no matter what. I tolerate that so well; because if it’s something not in my hands then why would I stress about it. Also, I really enjoy my own company.

However, now that I’m older and I have never been in real relationship it makes me sadly alerted without me asking for it!. It flames questions in my mind “maybe I have to do something?” “Maybe I need to travel more” “maybe I have to put myself out more” “maybe I’m just different” “maybe I need to pray more”…. I stood in between~ calming myself and wondering when will my body grow out of this?. I don’t want this type of reaction because I’M FINE ! I’m fine I know It’s soooo sweet and beautiful I agree and I’m so happy for others -wish them all the best, may god bless even more- and I believe it’s written! If it’s happening it’s happening.

I feel so embarrassed by this !
I really don’t want to care~ and while my mind is fine! My body keeps triggering itself!!!!
