I need some advice of how to chill and stop intrusive thoughts.  

So my anxiety has been fairly managed for close to a year.  

To keep it short - I was basically left in a dark basement as a toddler by a babysitter every day for quite a while.  
I was terrified of the dark and noises I would hear.   Logically what I was hearing was probably mice.  I didn’t explore.  My estimation is that I was between 3-6 during this time.  

I am now 31.  I have recently been finding rats in my house.   It’s an irrational fear that triggers a ptsd response from that time.  I used to have nightmares where I was seeing myself sleeping and there were rodents on me.  I could FEEL them on me, but I was viewing myself sleeping.  

Since they have turned up I hate going in my basement.  I have gotten two in traps.  But ive been jumpy.  My dogs foot touches me and I jump and panic.   I swear to shit I had one in the bed with me but I think I was half asleep and it wasn’t real.  But now I cocoon myself in a blanket and every time I get into bed I get goosebumps and swear I feel shit.  

Im sick of this.  This panic induced fear is new to me.  Usually anxiety is just situational based and an accumulation of many things.  I use fidgets and I’m good.  This is new.  I don’t know what to do.  Im afraid of my own bed, my own basement, going to the driveway… and I feel like I can feel them on me all the time.  It’s like how if you find a spider on you suddenly everything feels like a spider… except it’s rats.  

What can I do to just stop the panic.
