"poor service twice - dè ja vu"

I've been recently suffrring from very sleepy spells after ive eaten meals and through out yhe day cant stay awake, yesterday it became extreme and I was on my way home so I decided to go to a and e, why did I bother, so I got there gave my details checked myself in was told 3 hours wait I was like ok because from my side this iasue I was having was not normal and morelike an eemergency that needed medical help, time went by and I was called out by a nursefor a general check up so she took my symptoms, from my own research what I was feeling could lead to, hypoglycaemia, diabetes, low iron levels non of whivh I have ever been a sufferer of, so then the nurse goes you will be seen next, hour went by seemed like they forgot babout me so I enquired and 15mins later a doctor called me out, he checked me out and we had a chat about what I had eaten and how often this happens to me etc, I was like mate I jus don't feel right my head and my eyes are not normal, then he politely fobbed me offby saying you should go to your gp, I was like u being serious and he goes they are more equiped then we are, I looked at him in amazement and walked off, this is the nhs we have in this country then I see no hope, if the a and e cannot assist such issues why dont you make it clear from when a patients arrive instead of making us wait like 4 hours to be told have a paracetamol and go to gp, worst service I have received I dont think I will ever visit this place again
