How do you feel when men honk/holler/whistle/or hit on you from their car?

Sorry its so long...

So, today I was walking outside at like sevenish. I do this for the exercise an to get my body moving. It has happened many times where men have hit on me from their cars. I have been whistled at, I have been hollered at, they have said,"hey girl what's your name?", they have honked at me several times, an what seems like many other attempts to get my attention, and unfortunately they do because honking at me scares me. When I do this I feel scared, afraid, and little. They could get out if their car easily and walk towards me, take me, follow me, and its just so disrespectful (in my opinion) when they do these things. Some back story: on December 23rd of this year, just a little under a month before going to college, man drove by me while I was walking home from buying a snack from Fry's. I honestly didn't think anything of it but I wore some workout leggings, a sweatshirt, sneakers, and my hair in two braids. I felt comfortable and relaxed. I didn't feel sexualized at all, until this man stopped his car(and until someone made me feel horrible for wearing leggings. Pretty much making me feel responsible for what I'm about to explain. Let it be known I'm very close to this person and love them a lot even though they made me feel like it was my fault.)and started talking to me. Well, soon, while he was talking, I noticed him playing with himself. After he asked if I wants to join, I ended up telling him goodbye. He then proceeded to follow me. I got what i can only realize was a panic attack. I felt like I was in a horror story. I never felt so Afraid in my entire life. I thought he was going to rape me. Anyways, this is probably why I feel self conscious and fearful when they hit on me from their cars. What do you ladies think? Am I overreacting? And what should I do to protect myself or make myself feel safe/Better again?
