It's no problem, this problem is certainly bigger than participation in a community. Don't worry about it. There's no expectation for you to post or participate, but from my end, the expectation is to help people out when they need it.
I've had an FC charity account in mind for a while, and I think you'd be a great person to benefit from the HP that will be collected over time (once the account is opened). That one's going to take a lot of time, since this is all grassroots and thus far, from my pocket, but we'll do our best. I know that, given your time frame of suffering, that's painful to hear - but our best is what we will do!
Peace & love - no need to reply, preserve your energy.
