I have a question about abdominal liposuction.

I'm 155cm and 46kg.
 Everyone says I'm slim, but
 my protruding and sagging lower abdomen is so stressful.
 I think it's
 even worse since I gave birth. I tried Carboxy's shareholding body refitting, but
 it wasn't very effective.
 Think of the money I spent on management fees for the past few years. I'm thinking about getting liposuction from the beginning,
 so
 I'm looking into it, but
 I have a few questions:
 
1. Can I go alone on the day of the procedure?
 2. Will I be able to lead a normal life from that evening?
 Even if it's not going to work, is it just a daily routine of taking care of the kids?
 My mother lives nearby, so can I avoid getting caught?
 3. We are a weekend couple where the groom comes once every two weeks. I want to do it
 without telling him, but if I do it on Monday,
 I won't get caught, right? I'm going to avoid it because I'm on my period
 
. Ah.. It's my body and I use my money, but
 I don't like it when other people think of me ㅜㅜ
 But it's reality, so I ask my comrades~~ Please.
