Disgusted with my body

I'm 2 weeks pp and I have soo much loose skin I had my son by c section as he was 11lb 5oz and I struggled having him naturally. I was carrying big I lost 2st in weight off him placenta and waters so far I still have a little swelling and water retention. But now I have so much skin hanging there I'm disgusted in the way I look my boyfriend won't really look at me now properly when I'm getting changed before he would stare now he would glance and look away as though he looked at something he shouldn't or didn't want to see this was my second pregnancy. I knew I would put more weight on but I didn't gain weight I just gained stretched skin from a really big baby and I just don't know what to do or feel. I know it happens and I'm proud of bringing my son into this world I love him so much but its the aftermath of living with the skin for the rest of my life and I'm only 23
