I can't say don't feel that way. Your feelings and concerns are valid. To say anything to get you to disreguard your feeling would be to say I do not take them seriously.
You have every right to feel stressed. You have a lot going on. You have no mate to keep you moving forward, to give you a hug, to give you a kind word. (that is an assumption since you are going threw divorce) It is a dog eat dog world out there. We walk out of our safe homes daily into sin and insanity. There is no shame in feeling stressed.
Bad feelings are like cancer, they spread. The more you give into thinking about them the more of your life they seem to gobble up. If you asked your kids are you a bad dad I bet I know there answer. If the dishes pile up will it matter in eternity. If your house is a mess will it matter next year. (only if you get rats ) So the things that seem like big monsters now are really tiny lizzards. Godzilla started out as a tiny lizzard you know. Someone fed him way to much. Don't feed your problems to much. Infact kill them w/ kindness. Only feed them positive thoughts. I know easier said then done. But it is worth a try.
