Sinus problems

Hello I have been having a number of symptoms including eye discomfort, blocked nose / sinuses, fatigue, brain fog, iritability and depression.

This seemed to start last year when I moved into a house with alot of mold in it. After I left the house the syptoms remained.

Recently I started using a product called sinofresh which is said to be antiseptic and kill mold in the sinusesn and I am feeling better, my nose isnt as blocked, I am no longer depressed but I still feel tired and foggy some days and I still have eye discomfort. Recently also I have been having a nasty taste in the back of my throaght, is this a sign that my sinuses are finaly draining and I will start to get better soon?

I have also considered the possibility that I may also be alergic to dust (as my mum is) and I am still not sure if the mold has caused these problems. I keep going to the doctors but they havent done any tests and keep sending me away with different prescriptions. I wish somebody would clear things up and tell me what is most probably wrong and give me some advice on how to fix the problem.
