21yo girl looking for a place to live in OC SoCal

So I just got told that I have around 30 days left at the place I’m currently living. I have been sick in bed for the last week and subsequently been unable to work, my pet just died, and this was a nice letter to wake up to today.
I have been looking for other places online but I thought I should hit tumblr up as well.
I am looking for a room to rent, preferably around 6 months minimum. I can pay $600/month (negotiable). I have a stable job, no pets, no other responsibilities. I’m a cool person and am very amicable, respectful, clean. I go to Disneyland, play video games, sew and cosplay for hobbies. I am never late on a payment and am willing to even housekeep/babysit/etc.
I currently work in Lake Forest, and would like something nearby (Irvine, Mission Viejo, Rancho Santa Margarita, etc.) but honestly anywhere is great.
I need to move out by August 31st.
If you could please signal boost, I would appreciate it. I don’t want to end up on the streets.
