hey, welcome to the club!

There's a ton of great advice here, but I will add what is working for me, with a disclaimer: I do not have it all together. I'm just trying to reach a point where I can live contentedly, happily. And I'm not 100% there yet. But I'm working towards it. What I'm about to tell you is a process which I have been slowly working up to for the past year or more.
1) For low energy: I try to make sure I am eating enough calories, quality calories, not junk. If I wait til I'm too hungry I eat junk. I had to supplement with iron for a long time before I reached a point where I only have to do it during and after my cycle. I take a vitamin B complex and vitamin C when I need a burst of energy. I just started taking cod liver oil for the vitamin D.
2)exercise: I try to work out 3 times a week at a minimum. We joined a gym that has childcare, and to motivate myself I reward myself with a long shower and primping time after my workout. Now that the weather is nicer I'm also trying to get outside with DS for walks each afternoon.
3)decluttering. Set a goal, a small goal like, get rid of 1 thing each day. Freecycle is great for this, people will come to your house and pick the stuff up. If you can't do that, get a bin, fill it, and every week drop it off at a charity shop like Goodwill. Just get it out of the house! The less mess there is to clean, the easier it is to clean.
4)make your priorities. My priority is the kitchen. I do one big clean while DH is giving DS his evening bath, and maintenance the rest of the day. Everything else, well, I do it when I can. I try to do a load of laundry every other day. DH cleans the bathrooms. We split the vacuuming. I pick up the toys occasionally. I never dust. I hide messes. I hate mopping.
