Doing it (mostly) alone

hi everyone
I'm a 36 yr old SAHM to a wonderful 7 year old boy and a gorgeous 4 year old girl.
I'm married to an amazing man who sacrifices much by working in another country so that we may live well here. The last four years or so he has been on a 10 on /3 off contract (that's 10 weeks there and 3 weeks home with us).
I'm not going to lie to you, it's been a challenge and my eating habits have taken a knock. Moving to where he is isn't an option, he's a contractor and while the last four years have happened to be in the same place, it's not always a given. He has employment until August and after that hopes to start a business here.
I've been using MFP on and off so haven't gained anything but with my erratic food choices I haven't lost much either.
I'm currently 85kg (around 185lb) , 162 cm tall (5'3") and my goal weight is 60-65kg (132-143lb). I use a Misfit Fitness tracker and intend adding a bit of Zumba, yoga, walking and some body strength training .
During a bit of a down period last month I made the mistake of deleting my account , but am back now , and am looking for friends who wish to give and receive support in this journey of ours.
