Hey Dj -
Glad you're here.
Barre chords are a challenge for everyone at first - especially if you're playing acoustic. For me it's a little easier on a Les Paul - scale length perhaps? I heard somewhere that string tension on the longer scale electrics is a bit lower than say, a Tele.
Try moving your wrist a little further underneath the neck so as to position your thumb at or a tiny bit lower than the midpoint of the neck.
