Anxiety

Okay I know how silly this will sound but anyway...

So I started uni two/three months ago and it wasn’t a great start for me and it has bought a lot of anxiety/worry out of me that I didn’t know I had.

For example I’d say the last 3 weeks I’ve been fixated on the fact I’m gonna die one day, it’s all I can think about when I try to sleep and then I’m basically to scared to sleep so end up staying up so so late. And because of this I’m also worrying a tonne about my health and if I’m okay and noticing every little thing about me... thinking I’m really ill or there’s something sinister wrong with me.

I think my brain is making up more and more symptoms the more I think and worry about it if I’m honest

Idk how to stop it, I’ve never never worried like this in my whole life and it’s not exactly pleasant.

Any tips
