Is it normal that i'm always ill?

You may have a low immune system or not getting enough vitamin and minerals. Go see a doctor and have tests to find out why you're always ill

Have you seen a doctor? What's your diet like?, etc.

Drink orange juice, eat your greens, consume milk, exercise, meditate, clean your house, keep good hygiene, maintain stress levels, cut back on the sugars, and drink plenty of water. If it's viral, eat chicken noodle soup. Also, take multivitamins.

I'm wondering what your home life was like growing up?

I think you have food allergies! Try stopping dairy, especially drinking milk, eating cheese, yogurt, ice cream. I don't seem to react as much when it's a minor ingredient, but you might be even more sensitive to dairy. Get tested for other food sensitivities, like gluten. If your gut is reacting to gluten, it will make you sick because you can't absorb nutrients. I was sick my whole life until I was told I had a gluten problem and I stopped eating all the foods I react to. Even though I can't eat gluten (wheat, barley, rye, etc), nuts, and restrict dairy, life is finally worth living!

find it hard to breathe, blocked nose, sore throat, eyes watering

What exactly do you mean by ill......describe your symptoms?

well I've got a check up soon anyways, where I will have a jab and my urine tested, I have been stressed lately aswell, I have never thought about taking vitamins/minerals so thank you:)

dunno.
