Talk to Pediatrician on Psychiatric Issue With Child

Assalaam u alaikum wa rahmat ullahi wa barakatuhu. My son age 6 was absolutely normal and healthy.Few days ago his behavior suddenly changed for no apparent obvious reason.Only reason that we can think of is that due to closure of classes due to coronaa lockdown,he's probably bored.Issue is that he's become over hyper.he is all the time weeping and says that he will only share his feelings and fears with his mother.He was mobile crazy and used to watch mobile all the time.But now he is afraid of mobile YouTube etc and says that when advertisements etc come they get fixed in my brain memory and my brain is overoccupied and I can't get the memories out of my brain.he also keeps asking questions about very old times like cricketers and cricket records of decades ago even century ago and he's learnt too much old information by heart.Probably he's gained too much information more than he can tolerate in mind.He also complains about pressure slight headache.He has stopped enjoying life.All
