Welcome, hope you get some relief from this site. There are a couple of things I think you ought to know. First, chronic pain grinds you down, and you'll feel miserable in general. The only way to improve this aspect of your situation is to accept your life as it is and "learn to live with it". I know a lot of people say this but it is true. If you can help out and run errands, you can also have a social life (I'm talking from a medical point of view, not a financial one, although I'm sure there are always solutions, I don't believe in a "no-win" scenario). That people are irritable is logic as they can't relate to your medical problem. The general idea is that a person in pain is someone who can't function any more and is occupying a hospital bed. If you can still run errands, etc., people conclude your pain can't be that serious, thus you're a parasite. The reasoning is logic but incorrect as we here all know.
On the other hand, you should always keep things into perspective. Your pain is not "unbearable", otherwise you really wouldn't be able to stand on your feet anymore. Don't get me wrong, I'm not denigrating your pain or your situation, merely stating a medical fact. If you think the pain is "unbearable" and you're going to die, you most likely are not. If the pain really gets too much, you pass out; when it still increases, you wake up again ... they you die from the pain (but by that time the pain will most likely have paralyzed you literraly). That's what I mean by keeping things into perspective.
Nevertheless I suppose the psychological pain, the pressure, is the most serious problem. Yet from a practical point of view, are you capable of living alone? Can you take care of day to day maintenance of your household? And of course, will this not limit your social life even more?
I'm sure that here, on this forum, you will find help, advice and friendship. Take the time to post and read, this at least will get your mind of things and don't rush into anything suddenly. We're here to help.
Keep us informed and please tell us a bit more about yourself (if you fell that is appropriate of course). Always feel free to e-mail. Take care.
