First Peter, are you dedicated to Father Satan, and I do not mean it rudely, I'm just asking a general question as a build up to my next point.
My next point being which you will easily understand if you are dedicated, you're possibly experiencing enemy attacks, primarily from greys( a race of enemy aliens to humanity that plague us.)
If that's not the case, then you probably have some issue with them yourself. One thing I would recommend doing is this, sit down, where they aren't even if ya have ta go outside(and I speak from experience, because I have the same living condition) and question why the anxiety happens. And it may take some time, but inquiry is a HUGE part of spiritual satanism.
If you are dedicated, there are a number of things you can try to resolve the problem including the above idea questioning it.
First, clean your aura often. Second build a strong aura of protection twice a day.
And there are other methods you can try, but you have to clean your aura, and make an aura of protection everyday, starting now. Here are links for cleaning your aura, and making an aura of protection.

Now aura of protection:

Never mind the foundation meditation for now, because if you are not dedicated it's not advisable you do this.
I'll give you another useful hint because it's the best way I know how to write it as your situations are unique to yourself, anxiety comes from multiple sources, although not a bunch at one time, usually just one. Hope this helps.
HAIL SATAN!!
SAY IT LOUD AND PROUD!!
