Dealing with Unexpected Anxiety After Graduation

The first thing I suggest is trying to find out what helps reground you. Hugs, plushes, pets, smells, these can help pull you away from your brain's attacks. After that is just getting people you can trust to tell, "I have anxiety, I will shut down and have an attack sometimes, this is what it looks like, and this is what helps me stay grounded. If you see me doing this, do the thing that helps, or get me to somewhere I can do the thing myself"

Something that helped me with anxiety was accepting it fully when I started feeling very anxious. I noticed anxiety got worse when I focused on making it go away and passed quickly when I acknowledged it and reassured myself that it's just a natural function that won't hurt me. Highly recommend looking up Therapy in a Nutshell's anxiety videos on YouTube. They literally changed my life
