I have double eyelids, but they are going well.

I have double eyelids. I have them , but they are very loose ㅠ.ㅠ So I used to make them and go around with them . Moreover, my eyelids are thin, so I have multiple double eyelid lines, and the upper part of my eyes tends to droop. My eyelids tend to sag... When I go for consultation or surgery, I make double eyelids. Would it be better? Last time, I went to get a consultation without having double eyelids done, and the doctor only tried once or twice with a stick to make double eyelids. Or would he take care of it for me even if I didn't get double eyelids done, since he's an expert? Well, if I do the surgery on the double-layered lines, they will get thinner later and become double-layered, so should I ask for them to be made thicker than the double-layered lines? The thought of double eyelid surgery, which I will have to endure for the rest of my life, makes me feel scared and worried...
