Introduction, Looking for new motivation and accountability

Hey everyone, I'm a 23 year old sahm to a 2 year old. my husband is currently deployed and my goal was to lose 40-50 lbs by homecoming well i'm down to 166 from my starting weight of 180 with moderate exercise and taking a break for all of november due to a kidney stone and all of December because the holidays were insane but i have an all new motivation to be at least to 145 by homecoming possibly less but my main goal is to get into a size 10 comfortably or even an 8 or less, I can get in 10 but they are tight. When i lived in cali i had accountability buddies and workout groups, well now i'm back in my home state of utah and have no one because they are all good with how they look or don't have the same motivation i do and always back out at the last minute, I'm the type of person who needs to workout with someone or i get bored easily and give up after a few weeks. Not this time i'm determined, I have to Shock my husband who doesn't even know i've lost as much as i have let alone how much i want to lose, I will make him speechless, and honestly i have to show up an ex friend who told me i'd never lose the baby weight. 20-30 lbs in 3ish months. doable? i believe it is as long as i stay motivated, hope to meet some new people.
