<human>: I am 19, female, recently moved to the West Bank. 

My question is, recently whenever someone gets near me or even tries to speak to me, my mind goes into panic and I immediately get angry or start getting uncomfortable. 

A few hours ago, my mom came up to me (I do not have a good relationship with my parents), and she started asking me what I wanted for Dinner, and generally being nice and for some reason I became paranoid. 

She started poking my legs because I was ignoring her and for some reason I burst into tears, (angry tears), and I started flipping the fuck out. 

This has never happened before, this type of response to being touched. 

I don't know if this can be explained, and not many other subreddits have been helpful, but I would appreciate any input or idea as to why I reacted this way.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Mom poked/tickled my legs and I immediately started crying and my heart rate increased, not sure what the fuck is going on.
