Because family support would really help me stick to a lifestyle change. Having junk food in the house is too tempting but the others feel they don't need to give up these things.
Agreed, but does anyone have perfect conditions for losing weight?
Like any addict having temptation in the way is likely to cause a relapse and I do consider myself an addict.
Fair enough, so it might be worth thinking about how other addicts give up smoking, drinking, over-eating, drugs etc because they do so every single day.
I also struggle, as an autistic person, to go places on my own - so even when my arthritis isn't flaring I can't really go exercising without someone to come with me. Cycling is something I can sometimes do even if my arthritis is flaring but I need to have someone accompany me because I'm not very good at going out on my own. We don't get any financial support to pay for someone so I rely on others.
So, how might other people in similar situations have overcome these barriers?
It's easy for neurotypical people not to understand the need for others to support and actively help/do when an autistic person is trying to change their lifestyle. I get very anxious at change and even knowing it needs to be done doesn't make it any easier. I can't really explain better than that why I can't do it alone.
You are not helpless. You are capable of identifying what support you are currently lacking (your last post). You are also capable of reaching out for that support (starting this thread). I hope you can see that I'm trying to challenge your belief that you can't lose weight on your own. A) Are you sure you can't? B) Do you actually have to be on your own?
