His health problems includes these chronic headaches which he takes medication for but recently he started having these waves of anxiety. He has never been diagnosed with anxiety so its been very scary for him because he does not know how to deal with it. I've been doing my best to make sure hes comfortable and have told him to vent to me because getting out his thoughts have been helping him. Before I go more into this I'm going to give a little back story because I feel the more information the better. Other than the headaches he vaped A LOT with high nicotine. After he started feeling anxiety a week ago, he stopped and has also made the effort to eat healthier and such. He also used to have a cyst on the side of his head which he got removed a while back. He's gone to the doctors multiple times about the headaches but it runs in the family so he didn't take it as seriously as he should have, the doctors also didn't feel any sort of scan was necessary. Now that it has gotten worse, we went to the doctors again and we are going through the authorization process of a scan to see whats going on. The process has been taking long and my bf has been in high stress and it really sucks to see him suffer. Even though I'm doing what I can to be supportive, I was hoping to get some ideas or tips to help calm him down when the anxiety hits him. Hes been stretching out and writing things in journal to help himself get by until the feeling goes away. I've even written little encouragement notes in his journal in hopes it'll make him feel a little better if i'm not physically next to him. I reallllllyyyy wish they can scan him already so we know what to prepare for.

TLDR; I need advice on how to help with my bf's anxiety.

A lot depends on how your guy reasons. Does he like facts? This article and study might be reassuring for him. They both show that the vast majority of scans for headaches show nothing serious.

If he responds more to emotional appeals, you might talk about meditation, breathing or other stuff like that. Check out this article:

Finally, its not your job to fix his anxiety. Certainly offer support and listen to him when he needs to talk, but if its getting really bad the best option, if it can be done, is for him to see a professional. Don't know your situation, but if he works or goes to school, he may be able to access counseling services.
