I don't think people here ignore you, in S&P at least... Roll Call can sometimes be quite fast paced & responses can get lost but that doesn't mean we aren't reading your posts or thinking about you... equally, sometimes it can be quiet but that doesn't mean people are ignoring you... it just means they aren't around! It's just forum dynamics... I see the same on most forums I've been a part of, it doesn't reflect on you.
Trust me, we do care...
PS - Quite a few people here say this sort of thing from time to time... I think sometimes the illnesses we have make us feel isolated & unwanted, so you have to do your best not to listen to these negative thoughts.
