Baby weight

So I’m trying to lose weight after having a my daughter in November she passed away when she was 12 days on and since then I’ve been feeling really negative about my body wanting to look how I was before I was pregnant, I gained 30 kilos while I was pregnant so now I need to work hard to get it off, ive been working out and calorie counting but the weight doesn’t seem to be coming off I want to get back to what I was before which was 60kilos and at the moment I am 84 kilos

I used to look like this

I was confident in my body and happy with how I looked but now I am like this

And all I want to do is just lose all the weight but I just can’t seem to
