jumpy and flinching

[8bitAnalog]

does anyone else have a problem with this? there's been times when i've been in public places and when there is a loud or sudden noise or something pops out in front of me I will jump from being startled.I've even been jumping at moths flying around my room before if i'm not aware of them. it's like i'm constantly on edge sometimes. another thing I get which I think is more common is flinching when I am trying to get off to sleep.although its not consistently every night, sometimes its really bad like a few times before I finally get off to sleep and often it draws me out of me getting off to sleep and I end up waking up and not being able to get off again for a couple of hours.

I used to when I was younger but I trained myself not to. I used to get embarrassed jumping out of my seat when watching thrillers or horror films so I thought I'd better do something about it.
