Struggling with my cat allergy

Hi everyone,

when i bought a kitten from my aunt i didn't know that i had an allergic reaction from my cat and after 9 months i'm realizing that maybe it's my cat that's causing this allergic reaction, and i was right about it 

I own a Siamese cat for about 1,2 year.

after 1 month my nose suddenly got stuffed and this is been hapenning for about 1 year. I really don't want to find my cat a new home because she's a part of my family now.

These are the symptoms i get :

1.Stuffed Nose.

2.Itchy Nose

3.Sneezing, followed by

4.itchy throat after sneezing

5.Eczema on forehead. it's not extreme tho, it's just 3 or 4 dots, that's all 

But having a stuffed nose for 1 year is really uncomfortable, instead of breathing through my nose, i'm breathing MOSTLY through my mouth.

At this point my mom thinks to find a new home for my cat, cause of my cat allergic.

i'm against that decision, but can't say she's wrong.

If i can't find any good medicine or tips that would help me through this allergic reaction, then it's time for a new home for my cat.

Because after all living a comfortable life is important.

What do guys think, how can i minimize my cat allergy?

I actually wanted to ask this for some time now, any tips are welcome.

I mostly get stuffed nose, everyday basically.

p.s I'm from Belgium, so sorry for my English .

Thanks in advance.
