That's a really heavy burden to place on a child. Sure when they're really young you'll be the centre of their universe. A superhero that can do no wrong. But eventually they will grow up, and become their own people. That process often involves outright rejecting you and being really hurtful. If you have a fragile sense of self I'm not sure raising teenagers will make you feel any better, they can be godamn mean.
Also your kids should NEVER be responsible for your mental health and self esteem. It's incredibly unhealthy and you will likely end up raising broken adults because of it. Honestly, save yourself and your potential future chlldren the trauma and heartache and do the work it takes to deal with your issues. It will be hard, but believe me it's a piece of cake compared to the pain you'd be setting yourself up for later.
In addition to what people have advised so far, I can't stress enough how important rest, and especially sleep is when you're ill. Whenever I've fallen ill with a cold, flu, cough, etc., I find that if I try to fight it and go about the day as normal, the illness lasts much longer. If I try to sleep it off, I get better a lot faster. If you can, and especially on the first day, don't go to work, don't run errands, and especially don't go to the gym/exercise. Good luck!
