whats my body telling me

Well, basically I don't have medical insurance so going to a real doctor at the moment is abit too pricey. So I am wondering if someone on here could possibly help me out.

so I would say for atleast the last 3 years I have been experiencing these symptoms:

- shakiness almost to a point where I feel like I'm either going to have a panic attack or faint, I also get flustered in the face and feel dizzy before meals.

- after I eat I feel extremely tired, listless and I just cant concentrate. I even slur like a drunk person sometimes after i eat and my mouth gets quite dry and on most occasions this is all accompanied by a head ache.

- I would say that after a few hours of eating my meal once the tiredness has somewhat worn off,  I feel bloated and my stomache actually aches,

I have also been getting lower back pain recently but don't know if that has anything to do with the problems
I'm experiencing.

These problems do not happen before and after every meal but definitely frequently enough in the week to set my body alarm bells ringing...

Erk!  If your worried about the priceyness of a doctor and your looking to do something on your own, I am only passively going to recommend something.  The reason why, if left unattended what ever is wrong is going to get serious.  It would be worth your time to research diabetes and how to test for it on your own.  Keep in mind your also checking for severity.  It might be if you do have diabetes you just might need insulin in the near future to live.

Second the above, but add you do need to see a doctor.  Diabetes is what it sounds like, but could be lots of things.  The only accurate tests for blood sugar or diabetes are glucose tolerance tests, which you can't do on your own.  There should be community health clinics around for people who can't afford a doctor.
