What can I do about my allergy to my cats?

I have 4 short haired cats varying in age 7 – 9 years old (two orange, one black and one grey/white). I’m very allergic and adopting them out isn’t really an option at this point. Basically, it’s like I have a cold every day. I am wondering what the best ways to reduce the allergies are…via products including medication (I live in Canada).
Currently, I use febreze allergen reducer and try to vacuum once a day. I rarely hold them because I just can’t handle it anymore; my partner gives them all the love though. I really want to bath them but don’t know if I can do so without being severly wounded ..lol. I’ve tried to start brushing them at several points throughout the years but they won’t stay still and don’t seem to get use to it.
Any advice would be greatly appreciated. Thank you :)
