Here in Argentina, there's an association that provides free obesity treatment. Here’s the link with all the information. I hope you find the help you need.
@BikeEnthusiast sorry to hear it. My brother also gained a lot of weight. It started as depression when he lost his job and he just ate unhealthy for many years. Do you have any weight loss plan at all? Do you have an unhealthy diet? My brother had limited mobility after a few years and had to go to a physical therapist and had to make a mobility plan.
Not sure if you have a treatment plan of diet and exercise but if not you should start a plan. You also may want to try therapy. That was key with my brother's morbid obesity. He got his mind right first and foremost which was essential and then everything else came together. He lost almost all of the weight he gained. It took 2.5 years but he lost it all and has never relapsed.
I read your other post @BikeEnthusiast about drinking and having a bad cold. It sounds like maybe you are going through a bout of depression. You should utilize resources in BA. Many good therapists there.
I am sorry for you. Many people are orphans but they found a way to be happy. Also people don't have blood relative family but they make strong friendships and they become like family. It is never late to make new family. Many resources here in Argentina and people to talk to. Here we have very many therapist and doctors and inexpensive.
