I'm sorry you're feeling so exhausted and low energy.  It brings home the point that there are often barriers to advocating for yourself - most of all it takes energy to fight doesn't it? 

But I'm glad you asked, I'm actually working on a post right now about how to get help advocating.  Some ideas for you in the meantime - ask a trusted friend or family member to be there for you when you're unable to advocate for yourself.  Bring someone along to your doctor's appointments to help - especially when you're feeling overwhelmed.  And there are actually professional advocates out there that will advocate for you.  Of course they cost $ so if the cost is an issue a friend or family member might be the best bet. That has it's challenges too, as we tend to feel like a huge burden and also it's not always feasible for people to come with us to our appointments.  But I think some people want to help and don't know how - there is the perfect way for them to help.  

I hope you are feeling better - each day brings something new - my hope for you is that the days get better and brighter. :)
