Cant Sleep- I think this is Trauma?

IF THIS IS... THE WRONG PLACE FOR THIS let me know please and I will just take it to the appropriate place but I am shaky and wide-eyed and hyperventilating at nearly 2 in the morning and I don't know what to do. My heart is STILL pounding.

tw: for drugs, blood (??)

About 3 hours ago, a stranger who was on drugs jumped our families fence and yanked one of our side doors open and tried to break the other one down. I'm a college student, at home quarentining right now and both my parents were asleep all who were awake were me and my two younger brothers who I love dearly. At first,me and my brothers woke our parents up and armed ourselves with kitchen knives and skillets- it was harder to wake my dad up as hes hearing impaired and needed help with his hearing aids.

It took a while for my parents to call the police as they just wanted to "wait for the man to go away" even though the police station is down the road. Eventually the police did come and found him 'tweaking on something' hiding in our backyard, scattered money all over our backyard and his blood smeared on our fence. Since then I've been RATTLED with anxiety and nervously scratchin at my arms- it really doesn't help that since quarentine started my therapy clinic has been closed. Ah, I miss my therapist...

Either way, I have no idea how/if I am going to be able to sleep...I've never been victim to a robbery before, I've never even had my own house until last year.
