I got followed home from the grocery store last night

Last night around 3am I went to the grocery store to get some medicine for a cold. I drive a red 2 door car so it's pretty noticeable. On my drive home I had this weird gut feeling I was being followed so I looked in my rear view mirror and saw a dark SUV following me. The SUV had tinted black windows but I could tell there were two men in it. I drove on my usual route home but they continued to follow me. Started to feel a little weird so I took a couple of right turns at random just to see if they were actually following me. They were. So I got really scared and drove into a nearby parking lot, as they did the same. I parked in a spot that had an open parking spot on the right side of me. They parked on the side of me in the empty spot-YIKES. At this point I'm terrified and have never felt so scared and alone. There was no one else around us. I quickly got out of my car and ran inside the store we were parked at. They didn't follow me in. Shaking and crying I explained to an employee what was going on and they called the cops. I waited inside for 20 minutes until the cops came and they said they had left the parking lot. I'm just glad nothing bad happened but its so weird and scary that they followed me all that way just for me to lost them when I ran inside the store. Be careful out there tonight.
