Cutting my hair off. Well from the line down... it’s so choppy it looks horrible these days

Let’s pray it grows this time, going back to my stylist of the previous 14 yrs because my hair hasn’t grown the same since the last time a parent from the team cut it- she did a good job it just stopped growing and add that to the fact that it’s falling due to health and medication issues...
wish me luck!

Should I do layers still? U shaped? Or flat cut style?

(Remember my hair is wavy)
