South African mom looking to loose 20kg

Hi all,
I am a South African mom aged 33 with 3 children aged 12, 10 and 8 - recently divorced for the second time.
I have been overweight since I had my children and never had time or finances to do anything about it - until now!
I joined the gym and MFP very recently and I am looking to loose 20kg plus (minimum goal - more would be great!).
I am looking to connect with anyone in similar position - I am on a mission and very determined but train on my own so some inspiration would be great!
