I am dealing with severe anxiety

So recently I have been dealing with severe anxiety and I am not able to do anything about it.

It's killing me from inside, for no appearant reason.

Whenever I get a notification on my phone it always felts like something bad is going to happen.

It has gone to the point where I start shivering and panicking and my blood pressure increases and sometimes I feel like someone will knock the door and ruin everything.

It's not about someone will harm me in a physical way.

It's about they (I don't know who) will ruin my reputation in my family.

And that is making me so hard to focus on my work I am living in a different city for work and finances has not been really great lately.

Can somebody help me I asked some of my friends for help but no one understood.

I make fake scenarios in my head of me getting shammed or people talking about me in a way that this guy is disgusting or something.
