Can't stop checking if people have replied to me

Hello , I am a 21 year old male , i have been officially diagnosed with ASD , I was wondering if anyone else has this issue. Once I get close Freinds or especially fancy someone. I will constantly check wether they have opened my message , if they have been online and not opened it. Or opened it and not responded I get very needy and message again. Does anyone else have this issue . If so how do you deal with it?
