First, take a deeeeep breath.
I was in your situation just 3 months ago, and I’m still getting back on track to a new happier, healthier minded me. Reading posts on this site honestly has helped me tremensouly. Also doing yoga for me helps, so I would suggest yoga or google guided meditation. Above all, cut yourself some slack. We can be so hard on ourselves and it’s easy to forget to simply take care of ourselves. I know it seems hard and hopeless, but it really isn’t. I fully believe that you can lessen anxiety to the point where you forget about it entirely. One thing I encourage you to look into is EFT, or emotional freedom techniques. Gala Darling explains it very well in my opinion. And just know that you aren’t alone. I’m 19 and in a very tough college program, and I totally understand what you are going through. Figure out for you what initially triggers the anxiety, and don’t fight it. Acknowledge it, let it sit for a second and try to listen to it. And then try to let it go. I think what helped me most is when I stopped fighting with myself, recognized I was anxious, and either talked to a support system or did something I enjoy like catch up on my TV shows or shower. Also, 7 Cups of Tea is a great source if you need to talk to someone. I hope you find peace with this.
