Will my inside cat be safe outside?

my one year old cat peed on the carpet so my mom rudely put her outside and now she has to be an outside cat.. ive had her since she was four weeks old and only goes outside when she slips through the door and i go get her right away.. but now she has to be outside all the time and is very picky about her water, she WILL NOT drink it unless it is clean and nothing is visible in it (dirt, cat hair, etc.) im really worried she doesnt know what to do or shes scared :( shes been outside three days now and we live in the country so we have snakes and coyotes so im worried. she stays on the porch with two other outside cats but im worried shes gonna hate me b/c she does get that way, and im worried she wont know what to do
