How to deal with hypochondria?

Thank-you.
I am so glad there are people out there who care about people like me. However, I am afraid that even if I do not consider the issue of possible effects from medication, seeing a therapist is definitely out of the question because if anyone finds out then I will likely be no longer myself to them, I will be "insane", the word will spread quickly, and I will end exactly like my friend sooner or later, because that is exactly what happened to her. Don't get me wrong, she wasn't the idiot to ask for medication right away! But she was pushed to it by numerous relatives and friends, at one point, when I did not understand a thing, even myself, and now nothing could be done. Moreover, many of those people are still pushing her to keep taking it.
With a family and home to take care of and a job to keep, there is no way I can afford to let that happen to me. If I am not there, what will happen to my parents? My cousins? The home? Finally, the network of support for the many dispairing souls which only I can hold together? There is no one to take over after me. This sounds like excuses to someone who has not gone through what me and my family have, but I assure you it is not. If we managed to get to Canada and get a new life after all that has happened, I cannot risk losing it just because I can't keep myself together. One must go through what we've gone through before judging, although I would wish it never happened to anyone again.
