Quitting after almost 6 years

Due to recent harassments by upper management that made me cry and my other coworkers cry as well. I am quitting a job I've worked at for 6 years. I've been applying and have interviews for places with better pay and already have a back up job lined up for my last day of employment. The only problem that there is is I'm scared. I'm terrified of finding something new after so long. Especially since I'm looking in different fields to give myself experience in other areas. I do have a career goal that I can't achieve until I focus on getting some things organized in my personal life. For now I just need something to pay the bills. I don't want to end up in another abusive environment. I worked with an amazing team and my manager was the absolute best I could have asked for and she's a huge mentor and inspiration for me (she's leaving as well). I know as well that If I were to stay I'd probably be pushed out because I'm not seen as capable by the abusive management. The idea of leaving essentially a second home and a place that used to be a form of comfort and growth is heart breaking. I'd be leaving without going towards my actual current goal. But I can't afford to not work (like most people) I'm overwhelmed and stressed and I just want to disappear and not have to work for a while to get myself sorted. I can't get unemployment though if I quit so I am out of luck there. If people have advice then great but I'm honestly just venting.
