Its tough, but you arent that far out. Dont worry if you make a mistake. No single action is going to be the "end". If you say or do the wrong thing, just learn from it and move forward.
What are you doing to GAL, even if its inexpensive? Are there meetups you can join? Even one a week is great. What about taking the kids to the library? How about going to a friend's to share a bottle of wine or 6 pack and watch a game? Theres lots of ways you can get out for cheap....its just a matter of being creative. You NEED to show yourself that you are capable as a person and as a parent all by yourself.
