Zero weight loss after pregnancy

Im so depressed...Pre pregnancy i was 130lb and I’m 5”7. When I went in to labour I was 190lbs. Day after I gave birth i was 180lbs.I’m now almost 6 months postpartum and legit have not lost anything..still 180lbs....

I go for walks every day atleast 2km...

I try and eat really well, now I am going to try and go to the gym a couple times a week. I find it so hard to even find time to shower or sleep at this point nevermind leave for an hour or so to go to the gym. I also have zero energy. Ugh any other mommas in the same situation? I just want my body back or half of it atleast 😭

Forgot to mention I’m exclusively breastfeeding.
