Oversensitivity due to suffering through anxiety and extremely stressed and hurtful times...?

Do you ever feel like, maybe because you have suffered so much stressful & hurtful times, gone through pain, that maybe due to that you don't feel like getting out of your comfort bubble, whatever it is that it may be?

I mean, you know imagine how the 1st time you might have burnt your finger by accidentally touching something very hot and then retracting your hand..... And then the next time you just stay away from even lukewarm/slightly warm utensils? Because you're afraid that it will hurt you like hell just like it first did? I sometimes feel as though maybe it's coward of me to not even step out of my comfort just due to this. That I am maybe failing at life due to this. I feel I have become too oversensitive to pain that I don't even try anymore. Be it friendships, forming relations with other people. Infeel so tired I never even respond to people anymore. My mind becomes a blank slate or something. People tire me out. Do you feel like that? Sorry for the long post..
