Need advice. Think I was followed

I need advice tonight. Yesterday morning I started  work at 8 which meant I set of walking to work at quarter to 8. I walked past the shop and a guy walked out and was on the other side of the path and I started getting worried and then he crossed over on the same part as me and cause I was worried I turned a corner and I never walk that way and he did the same and then I crossed over again over a big stretch of the road and he crossed over and he backed off when I got quite a way down the road and so I didn't see him behind me but it just seemed really weird and I was panicking so much and nearly in tears and I've been left paranoid and scared all weekend so much that I've asked my boyfriend to meet me anyway I need to go myself. He might just of needed to walk that way but I wouldn't know cause it wasn't my normal route but it was weird that he only backed of as I got into our town centre. It's still pretty dark at that time too. I kept looking behind me so wether he picked that up and thought I better back of as am scaring her maybe. But in the morning I have to walk to work at half 7 again and I'm so so scared, I've been dreading it all weekend and I can't get a lift to work so I can only walk. If it happens again I won't be carrying my journey on to work, I'll be turning round to go home!  I don't want to change my route cause I don't know what it's like a different way so early and dark in the morning. What is everyone take on this and any advice  to easy my mind walking to work?
