60 day notice! Ugh! Help with security deposit

Well after 5 Yesrs the owner has opted to cash in on the equity of an Altadena Ranch Style Home. I paid my rent on Wednesday and got a sixty day notice on Friday May 3!
The anguish, the sadness, the fear of that initial realization was a tough pill to swallow. 
The girls have grown into young ladies Here. Claire moving on from High School to a budding career! Marina is looking forward to her senior year! 
I’m just so stressed and close to being overwhelmed! Thank God For Family, My Girlfriend Tori and cut to the Chase; my community of friends, musicians, workers, clients and Acquaintances! 
Im so embarrassed and even down on myself for asking for help. 
I make Pretty Good money. 
I make the rent money and pay all my bills. I chip away at debts and I take care of our needs and have money for fun stuff and family. 
But I can’t put together 2 times my normal income in the time needed to Come up with deposit and hardships of having to move! Hassles of changing utilities and time and energy needed to move! I FN hate moving!
So we as a family are hoping to use this format to get ourselves somewhere Safe and comfortable. I have work tools, we have pets ... and the big priority is staying in the school district. 
We are downsizing for sure but still desire a rental house. 
Again I feel like Crap asking  

You Know I will forever be grateful! Will pay it forward one day to others, be it with some Music, the successes of my kids or with a smile and I would give an extra money I have in the future to organizations such as the Eviction Defense Network to name one! There are folks in more dire straits than us out there. It’s happening every day!

Thank You So much!!
