I know you are drained, sick and tired, tired and sick...this thing is a pain in the ***. All you can do is keep pushing through, try to rest when the kids do, put your social life in when you can....out when you can't. Your family will get tired, stressed due to this illness. Stay positive. Keep working towards health and non dizzys.
Soon, after a few months of exercise...you will notice you can start adding life back in. Then you will look back and realize you were brave and strong and you are on your way.
All the best!
