grammer&word

hi
what is diffrence between myself & myown?
and “have been verb+ing & have been p.p” t00.
many thanks.

Myown is not an English word.

The former is the Present Perfect Continuous, Active Voice and the latter is the Present Perfect, Passive Voice.
I suggest you read something on Active v.s. Passive voice, here’s a good reference:

Please note the correct spelling of the word ‘grammar’.[YSaerTTEW443543]
