What could i do about my anxiety besides meds?

well you see, about 2 years ago this guy shot my dad and i was there and the guy hit me.. i always have flashbacks from that day and now whenever i see a guy that looks even somewhat similar to that guy i have anxiety attacks. i am always super scared now and i dont even like being outside in my front yard by myself because im scared something like that would happen again. i know that i am being a bit paranoid but still. it was a very scary day. besides going to like the doctor and getting meds or a therapist. what do you think i should do?
