I always try to remember to preview my replies, unless it's to a member that I'm pretty sure understands how I say things. (Still, others who read sometimes retort that I'm off the mark.)
Do your best. If you can say something,
anything I think it helps the originator of the thread. It can be very depressing to some to have many views of their post and no replies. It makes them think that what they said isn't worthy of reading, much more replying, imo.
A smilie face (or sad one) says a lot without words. If you can't give hugs ((( ))) or a heart

can you try and find something that will work as your trademark for having read and "understood" the message?
IMO it's great that you're here, and reading. But this site is for you too, and if your healing doesn't include replying yet, that's ok too.
((((everyone)))
