Practical help please to calm HA worries

[Massive worrier]

Coming off some medication and i am getting sickness bug type symptoms, feeling sick, cant eat, i stupidly googled and others have had horrible symptoms. I'm terrified! I went to my lecture yesterday and left half way through because i was scared of being sick. I have another lecture today in 2 hours and im scared of some of these symptoms starting up again. I feel drained and like i cant move and want to stay where i am. I know this isn't going to make it better! Also, i really don't want to miss my lectures!! I have had a look at a few TED talks which have helped, but still worried! I think i need to be told to just go and get on with my day but i'm not listening to myself. Please help

sickness bug type symptoms

Unless you have been sick, it seems silly to assume you have a sickness bug.

Anxiety can make you feel nauseous.

Go to your lecture again. If you feel sick again just ask to go. No-one there will care... trust me.

When you don't eat you feel hungry. Feeling hungry can exacerbate anxiety and nausea. Try eating something small, or having a milkshake. Thats what I do.

Yeah, your right, thanks. I had a bug 2 weeks ago and it was really unpleasant and having similar symptoms again makes me think it will start back up again!
Will have some toast and go, thanks for replying.
