I am so upset and need to get it out of my chest

I had an appointment for 2nd vaccination with my baby girl that is 4 months and when I got called in I asked the nurse about her eye as is constantly discharging since she was born. She look at me without checking her and told me she had conjunctivitis. I got i little irritated as I been to several appointments there about her eye and every time I got the same answer “ is nothing concerning and very common for newborns, keep cleaning it with water”. I told the nurse why only now I’m being told this after 4 months and she proceeded to tell me to go the pharmacy and ask for treatment at the counter without prescription and telling me that I should call gp for such a thing as newborns commonly get a lot of this stuff until are 1 year old and when she grew her daughter she only use water and that people are calling gp for a lot of silly problems such as “nettle stinging “. Sorry for my long post it might not make a lot of sense due to being still annoyed with her response. Was I in the wrong? Should I’ve not insisted on my gp to check baby eye?
