It is worth saying, now is the time to trim as much as possible from your expenses if you have not done so yet. You need internet and a phone, but you don't need cable or an I-fone X. Gym fees, dining, subscriptions, lawn service - these all go. It is temporary, just until you have income again. Throttle back, and your cash lasts longer.
I have been there. I finished my MS in 1 semester the last time I was unemployed. Severance + UI paid for a lot, but I had more expenses. I had a pretty healthy emergency fund, and it served me well.
