Memory loss can be caused by many conditions, including psychological stress, trauma, brain injuries, some neurological conditions, etc.
You should consult a neurologist to properly assess your symptoms and to determine whether an organic cause of the memory loss can be identified and treated.
Good luck.
As for being forgetful whilst talking, concentration may be goofed up from stress or illness or lack of sleep. Poor sleep can also be why you don't remember parts of your younger life. So, you could also have a sleep test done to determine if you have sleep apnea.
