Seriously DTM, it is very important that you have other adult interaction. It can be other men. You don't need to date. Maybe befriend parents that are involved in your kids activities. I understand that you feel guilty, but try and rethink your this. You need to at least act as if everything you do is great. I am going to repeat this You need to go out and interact with others. Have people that you talk to and text with on your phone. Reconnect with family or friends who you don't talk to often. Smile a lot. If you took psychology in highs school or college you will remember that not only do people smile when they are happy, but smiling actually makes people happy.
You need to do things that that are different than you are doing now even if it doesn't make sense. Just try something .. If you have facial hair, shave it off; if you don't, then grow some.
