I wonder if anyone can help me.

I have been having bizarre symptoms for a while. It started off feeling very thirsty and low in energy and just general feeling unlike myself and under the weather. Even though I am thirsty, when I drink I still feel thirst and just go to the loo a LOT. I also feel like my immune system is bad, I keep catching illnesses, get headaches and keep getting flu-like symptoms and rashes that never develop into a full blown flu.

 

I went to an endocrinologist and he told me I may have primary polidypsia aka implying I'm imagining it, which is definitely not the case. He checked  for diabetes insipidus and I don't have it.

 

Anyway, I tried to move on and ignore the illness but then I started to leak urine after going to the loo. It was not a lot but enough to be worrying as I am in my early 20s. At first this just happened once every 2months and now it is getting more frequent and close together. Anyone have a clue what this is?
