Hi there ~
I understand your concerns. I think the lightheadedness
, breathlessness, loosing weight, and having back problems are related to your having low energy and not eating right with being stressed. Though there might be other causes for these symptoms you probably are working yourself way over your limits. You also have insomnia
that needs to be treated. Please see a psychiatrist
and explain your symptoms. I hope you fix an appointment as soon as you can.
I hope this helped and I wish you the very best. Take care!
