Really struggling with and hurting over the persistent thought that I don’t bring joy to anyone’s life

I used to be able to bring joy to my kid when they were younger but now that seems to be gone. I can still make my wife laugh sometimes but less than before. I can’t really maintain any friendships and with those friends that I do have I don’t feel like I contribute to their lives at all. No one really reaches out to me and I don’t know how to connect with anyone apart from on the most superficial level. I wish I were a different person. Not sure how to go on anymore.
