Number of sysmtoms

Hello I am currently having these sysmptoms:

fatigue and irritable, also foggy thinking
tired eyes, sometimes itchy, sometimes feel puffy, often look red around the edges, sometimes vision a little blurry
My face feels full quite often
My nose is often blocked

Sometimes these symptoms go away and I no longer feel fatigued and I feel good :) but not often enough it seems :(.

This has been around a while now but it seemed to get worse when I moved into a new room last year which had mould on the walls, however since moving away from there these sysmtoms have not gone away. The house I am in now is very dusty.

I thought it was an allergy but I had an antihistamine and nothing got better. Any ideas on how I can sort these problems out and get on with my life, this has been going on far to long... Thanx for the help.
