Hate my job

Hello all, I’ve been at my current job for a year now and each day is worse than the last. The people are miserable and it’s a very small office with constant gossip and whispering. No one is supportive of each other and the manager holds no one accountable for anything. They will talk for hours while I do my own work and answer the phones and help customers at the front. They are also constantly late to or calling in.

Anyways, I’m currently having a breakdown in my car because I’m so miserable here. But I’ve applied to literally hundreds of jobs and no one calls me. I got my masters degree last year at 21 and it seems like that was all for nothing. I spend my days online applying for jobs and trying to avoid the negativity but it’s getting to me. Any advice at all is appreciated
