I am feeling absolutely fine about the current situation (as fine as I can be).
A few years ago I was pushed through a shop window, not going into details, but it was traumatic and by some miracle I had v minor injuries but was trapped for a while, while all the shards of glass fell around me.
Few months after this I was really jumpy around loud noises, this passed.
Few years later I had a minor car crash, wasn’t injured but the impact created a really loud bang, cue and loud noise, bottle bank why making me jump out of my skin. Settled down again.
Now I am at home working, perfectly happy but not going everywhere I normally go and in peace and quiet but it’s happening more when I do go out, unexpected noise and even when people come into a room I am in and I haven’t noticed. I am like that women in the Catherine Tate sketch who screams at everything 
I wonder wtf this is and am I not noticing my own stress.
I am really aware of my own mental health as I have a job where I need to be.
Has anyone else experienced this and does it sound like PTSD (or am I being overly dramatic?).
