My anxiety is through the roof...help!

[HCantThinkOfAUsername]

Someone came in my house few days ago. Started a thread about it. My own fault.
Anyway 3 days on and the shock has worn off, I'm obsessively checking the doors and windows are locked, I can't sleep, my heart is racing & I'm all panicky but tonight is the worst.
I can't stop crying, very jumpy; can feel a panic attack brewing.
Don't want my dc to pick up on it. Dp is on a night shift which doesn't help. Agh. What can I do? ! :(

The thing that usually helps me is checking each room one by one and then shutting the door once I've checked it. That way I know if anyone was to try to move around the house I would hear them.
If you have anxiety it might be a good idea to get some security lights/ cameras and a house alarm. Think I read your thread about when you found someone in the house and it's very unlikely the same thing will happen again the same week.
What do you usually do when you get very anxious?
