I know this is tough. Good for you for getting out and doing something for yourself with the shopping.
Sweetie, your feelings of obsessing over thoughts of your H and OW and your crying are perfectly natural. They are things I think we've all done at the beginning. It's hard to stop them. Someone else on the board mentioned the same thing about seeing all the happy people around them. I was just in the store the other day and was walking past the men's section. I wanted to stop and look at things, but knew my H wouldn't appreciate it right now. Let's add on top of that the fact that you have kids. That's a heavy burden to bear.
You said that you have few people to talk to. Do you have anyone? This board is a great place to come to, but I know that it's helpful to at least have someone close that you can talk to. Do you go to church? Could you talk to a religious leader in your church? Just a thought.
Hang in there. This is tough, but you've come to a good place. You'll get a lot of honest, but wonderful support here.
