do my bf really care for me at all?

ok, here is the situation. we went to a rehab to visited his Grand Pa, who had a surgery on his leg. For some reason when i stepped in the room, i feel uneasy and start to feel dizzy, i asked him to steped outside with me for few sec to get some air and water. on the hall, i passed out on the floor, just laying there for few secs and in that few secs my bf was knee down on the floor, keep tap on my face to wake me up, finally i got up and drink some water, thinking that everything is fine, i just need some water, but as soon as i got back in the room, i started to feel as sick as before, next thing i know i was almost on the floor,passed out again.,my bf and his aunt caught me and helped me to the chair. Nurses came, check if everything ok, at that point my blood pressure was low and i didnt respond to anything so they called 911. after that i recovered... the only think made me really thinking was ... at the point the nurse asked me to go to hospital for a real check up 'cause this was a situation they called " abnormal" , my bf was busted out and said " ... but it cost thousand to drive the ambulance...!" and the nurse was responed like " ... but if u dont get a check out, if it's a something, next time she wont come back to you again ..." ... at that point it was just make me embarassed and sad. feeling like he dont concern for me, but only the money. is my feeling was normal or im over reacted?
