Job change

So I currently work at a hospital five minutes from me making 13 base pay . We are always really short staffed an it’s been taking a toll on me having conflict with the nurses because I had to report a matter than it was pinned against me. So I’ve been trying to get into another hospital about 20 minutes away ,as flex an be able to keep my previous job as well. They called to offer me fulltime starting at 16$ an they’re union. I know it will be a better company to work for as I know a lot of people who work there. I just always get worried of change and switching things cuz what if it is worse an all. I have recently been dealing with bad panic anxiety so I’m worried if I take this job it will get worse an I won’t be able to push through it. I am always awful with decisions but what would you say?
