I used to think something like that(my pointer has some really weird extra fat... Ya I know, weird) that to, I used to not even can make a F chord like you, but over time I could, and Im at now where I can bar 6 stings, but still am not at that fingering chord levle to do anything else when I bar thoes six stings but anyway... You'll get there.
Or you can try to do it like furry lewis, use yor elbow or your hand to do it.
