Getting fit before 40!

Hi all - I just turned 39 last month, but am at my heaviest weight and absolutely refuse to turn 40 and still not be happy with myself. I have lost weight before with WW and it was great, but that has been quite a while ago and life has gotten in the way with two active children and a busy husband. I do not make the time for myself that I need to, and here I am again, starting all over. I would like to lose about 50 lbs and I am giving myself plenty of time to get this done. I have some friends on MFP already but that has been from past times, and they have either quit logging or I just don't seem to get much response/support, so I would love to add some new fresh faces that can help me to get and stay motivated. Thanks so much!
