Should I just stay to myself?

I turned 40 not too long ago and looking back at my life I feel hurt. Hurt that I've come this far without genuine friendships, a long term relationship to be proud of. I feel let down & used. Everyone took my kindness and ran with it. Never wanting me as a friend. Never picking me as that girlfriend worth keeping. I feel to just stay to myself and stop trying to make friends. Stop thinking there's a guy out there for me and just walk the rest of life alone. It all hurts in my core. 😔
