Does anyone else get this?

I seem to be feeling weak, shaky & tired most days at the moment and its really worrying me.

The best way I can describe it is that it feels like I've had a shock, say for instance, you were driving along and someone jumped out infront of you. Although you missed them it leaves you with a shocked weak/shaky feeling which (in this senario) would leave you after a while. Only I havent had any near misses, just going about my normal life, yet I regularly have this sensation!

I know anxiety can cause these feelings but because i'm experiencing it so frequently I'm worrying that its something else. My iron levels were low and i've just finished a two month course of iron supplements but they havent made me feel any different even though my levels are up now.

My husband always says I dont drink enough (3-4 med glaases a day!)the problem is that I never have much of a thirst and tend to forget to drink! but surely this couldnt be the cause?
