If I could go back in time

Regret is something new to me . I can't remember that I've ever regretted doing anything before, even if it had bad consequences , I took responsibility for it . the damage was only to me and no one got hurt , but now I know regret and it's awful especially when it concerns someone and not just anyone  , someone you love , someone you never wanted to hurt . maybe regret is new to me because love is new to me .
