Hug to you, sweetheart. Take a deep breath. Close your eyes. Roll your head forward, then circle to the left (keep your eyes closed; breathe easy). Roll your head to the back, then to the right then back forward. Stand up straight. Open your eyes. Make your shoulders drop in a relaxed way. Take another deeeeep breath. In through your nose, then blow out through your mouth.
Another hug.
You'll get a bunch of suggestions about making sure to take time for yourself and ask for help and get exercise -- and those are all good, accurate suggestions. Here are two small steps I'd like you to try: get in to see your doctor even if you have to take an afternoon off from work. If your kids were sick, you'd make sure they got the care they need, right? Well, you need care , too. Start with a visit to your doctor. Tell him what you've shared here. There are several vitamin deficiencies that can TOTALLY sap your energy. Are you getting enough iron, for instance? This leads to my second suggestion. Take a look at your diet and your fluid intake. Increase the fruits & veggies, even if you just leave a bag of grapes in your car & munch on the way too & from work.
By all means, treat yourself to some little thing when you can. Take a breath & enjoy your kids & your husband. The suggestions to get exercise & such are good. Try & fit them in where you can. But don't beat yourself up because you just can't get to the exercising or self-help parts yet. You will get there. Really.
I feel your exhaustion. I've been where you are and I've made it through. You can, too.
By the way, think of that really well dressed acquaintance with the perfect hair who invited you out. You may feel like a mess but Little Miss Put Together WANTS to spend time with YOU. There must be something there that right now you can't see -- but she does. Even with hair in a perpetual pony tail, an acquaintance wants to know YOU. Good for her for seeing beyond the frazzled-ness! And good for you for being a person someone else wants to know better.
Another hug. Take another deep breath. Hang in sister--
