Hi NotMeHere, welcome to DF.
Does your wife know how you feel? Is it something you would feel comfortable talking to her about?
Please know that you are not alone with these types of thoughts & feelings and a lack of friends and having issues with interaction.
Have you thought about speaking with your GP/family doctor about how you feel?
I hope that we can support you here on DF, this is a very friendly and supportive community.
Make good care,
Girly
