On this topic.
The fact that it is difficult for those around me to accept the illnesses of loved ones is not news to me. We go through all stages: rejection, anger, denial, bargaining, and exit. But this usually happens with diseases that are being treated. And this... This is chronic. Others constantly need to pay attention to you and help. It ruins relationships over a long period of time. How to maintain independence in life when you are forever bound by pain?
Everyone needs to come to their own way of handling this....the way that feels right to you and that is appropriate to your own circumstances and lifestyle and personality.
What I do is I basically never ask anyone to pay attention to me or to help, because as you have said it will ruin a relationship over time. If I cannot do something that really needs to be done, and with a very small amount of help I can get it done, I will ask a friend if they can help me.....but I always make it clear that their role is very finite, and that they should absolutely feel free to say no if for any reason they don't want to do it. I ask a person, each time, if they will feel comfortable saying no, and if they won't feel comfortable saying no then I don't ask. And the only person I will ask for this is someone who has already asked me for help a couple of times and I have been able to help them.
If I don't feel right asking for help at all, or it's a bigger job, I hire someone to do it for me. I don't have much money, mind you, so that means sometimes a thing has to wait while I save up the money.
If it is something like cleaning the house or laundry, I just don't do it unless I am having a good enough day to do it myself. Or, I do 1/3 of it one day, and the rest I get done over the next 2 days. I have gotten used to this and it's not really a big deal.
The other thing I do is never, ever talk about my pain to others. Ever. If they ask, I will say something mild like "Oh, it's been a bit worse lately", or, "It hasn't been as bad this week", and then I change the subject. It helps no one, least of all me, to go on about how much pain I am in. And doing so will very quickly make people not want to be around someone at all. I use my time with other people to talk about anything BUT my pain, and it's a great way to distract myself.
I maintain independence by these methods.
For me it's very important to get things done myself as much as possible, and also I don't have family or friends who can help me for the most part. I have lowered my standards of how everything has to be, while still maintaining a reasonable standard. I have gotten rid of a lot of stuff to simplify my home, which makes it easier to maintain.
These are the things that have worked for me. If you practice looking at things in different ways, you will find what works for you.
