TL;DR: Gained too much weight after I fell and broke my arm + couldn’t really move for a while. I have a lot of trauma related to sports, like I was forced to play football like any other Hungarian kid, and I was awful at it, which made others be angry at me for it, which made me reluctant to do it. Even if I manage to do it, I often get brutal, crippling muscle pain, which makes me fo it even less.
Since I"m Hungarian, I cannot rely on health care at all, especially mental health, as it was the very first thing that got cut, amd I cannot afford private care.
You said you can walk— keep walking. A little further each time. I usually do at least a couple miles a day, but it’s literally been 104 where I am, so I haven’t been able to go as far or as fast as I would like—and I’m gaining weight. 😕 So, yes, walking can absolutely help with your weight. Good luck!
