New to MFP - would love to make some accountability partnering friends!

Hi everyone, I'm new to MFP, but have heard about it for years. Two weeks ago I underwent weight loss surgery, and had the gastric sleeve procedure. Since early February I have dropped over 30 pounds, but am looking for a good tool to help me maintain the momentum I have, and to be able to track my nutrition (because that will be really challenging for me now that I can't eat much). My dietician has given me an 80g per day goal for protein, but my belly pouch is really small now so it takes me several hours to finish one single serving of Greek yogurt so I feel like I'm eating all day in order to meet my nutrition goals. I'm currently supplementing with protein shakes between meals, but I never feel hungry.

Right now, the two biggest challenges that I have are increasing my movement/activity, and making sure to track nutrition. I am terrified that my hair is going to fall out - a common side effect from nutritional deficiencies after weight loss surgery. I have a desk job so that doesn't help with my activity level, but a friend is gifting me with a year membership to her gym, so once I can build my stamina up enough to walk for more than 10 minutes at a time I'm going to jump back in and start with a trainer to get me toned.

I'm located in North Carolina, am 45 years old and have a goal to walk a 5k before my 50th birthday - and I know this is totally attainable. I have three children at home, including 1 with autism, and 2 with other behavioral challenges. I'm currently separated from my spouse, but he has been very supportive with this journey and we still live together as friends/roommates/co-parents.

Starting weight: 332
Current weight: 296
Goal weight: 145

Short-term activity goal: Walk for at least 30 minutes per day 3 days per week.
Long-term activity goal: Walk for at least 60 minutes per day 7 days per week.

Looking forward to making some new friends here!
