please help!

So I'm having serious issues with my anxiety lately. Not socially but just generally. I'm constantly worrying about everything. Like it doesn't matter if I solve one issue something else pops up in my head and I begin to worry again and it's ruining my quality of life. like for example this morning when I needed to go to work I was freaking out because I didn't want to be late but I had a lot of time , I ended up being early. Then I started to worry about getting the putbacks done at work and it became even more stressful and worrisome when more putbacks would pile up (I work in retail) . Then I was on my 30 minute break and I like shovelled my food in my mouth because I was worried about not having enough time to eat . I had more than enough time and gave myself a stomach ache from eating so fast ... I was worried about being late clocking back in and again I was early. And then I got home and worried about how I'm going to manage to get some tampons because I missed work last week for medical reasons and have no money. and then i was stressing about money. and then it was me worrying about getting the slideshow done for my sisters wedding. I stayed up until after 2am when her wedding is a month away still. and now that's done and now I'm worrying about what to get my dad for Father's Day and where that money is going to come from because I need money for my sisters bachelorette party next weekend. And then the worry transfered to how I'm going to afford my hair and makeup and other things at my sisters wedding. It's constant . I need to relax but I just don't know how to relax anymore . What can I do ?
