I think I have memory problems
That doesn't sound good. Maybe you should get it checked out by a doctor?
I have a good impression, but it's going to be a waste of time having a consultation with a doctor.
I'm sorry you're struggling with your memory, but you still have to take charge of your own health and go to a doctor. You can't cure yourself, you're not an expert and the more you delay the more your memory will deteriorate.
Everyone has memory problems..
It's not a waste of time to get something checked out by a doctor. Your memory is important and its better to get any issues taken care of before they get worse.
