If go and get something to help your brain relax personally. If you need to treat it it's ok it won't be forever
I’m really sorry you’re feeling this way. It sounds like your anxiety is making everything feel worse. The high blood pressure could have been a result of the stress, but since it’s come down, that’s a good sign. Try to focus on breathing slowly and calmly to help ease the anxiety. It might help to avoid looking at screens or doing anything too stimulating right now. If your anxiety keeps affecting your sleep, it might be worth speaking to a doctor for support.
I would keep an eye on it but also don't hesitate to contact your doctor and just let them know what's going on
