Its like the more I respond the more they get attached
That is the thing - don't respond!!! And then they do not attach
ETA as has been said here, try not to get personally involved with your sitters. Do the reading and move on. Have strong boundaries in place, rules for yourself and your sitters, and insist they be respected, or refuse to read. If someone is too negative for you to read, then tell them you will read some other time for them - don't be specific - or say you cannot read for them that day - and leave it at that.
