does anyone get scared when they get confessed to?

like I don't think am 100% ace but for some reason each time someone likes me am just as akward and scared as them. i also have this feeling of running away from them the momment they say anything like why isn't it normal to get confessed and just run away and not talk again untill you feel comfortable addressing it again. i have to reply to it and sometimes hurt you in the process.... isn't it easier to tell a friend that to tell me what i think about them and so on and you'll get ur answer... like ugh....
