Could you spot the errors please, and if unnatural?

Could you tell me if there are any errors and if natural?

1 You get paid a lot considering the number of hours you work.

2 I couldn't help but look at you.

3 If I came it would hurt me even more./I'd get hurt even more seeing you off.

4 I've been coming here longer than you've worked here.

5 He (had) started annoying me before the incident.

6 It feels like we were friends in another life/ lifetime.

Thank you
