Looking for Support with Joint Protection and Weight Loss

Hi! Got an ad for this app and thought it sounded interesting. I’m realizing it’s basically like a support group which honestly sounds kind of nice. I’m 27 years old and have been super active and very healthy my whole life. I don’t really have any major health issues but I am curious to see who’s “alike” to me! I think the biggest thing I am seeking advice on is both joint protection/mobility and weight loss as someone who lifts weights, exercises frequently, *and* also has a diagnosis of Hashimoto’s thyroiditis. I was just diagnosed last fall but have probably had it for years. I don’t have very severe symptoms other than likely having a shit metabolism and maybe some fatigue, but I have been having some joint issues recently in my left shoulder and hip. Unsure if these things are related but my orthopedic specialist suggested there could be a connection. Looking forward to connecting with anyone who has similar interests and may be struggling with similar issues!
