I am assuming you want some input onto this situation.
The advice I can give you, is to not do the readings. Do not do readings for other people unless you are completely comfortable with your abilities. They are flocking to you because:
a) It is free
b) You stated your readings end up being correct
This is like having a make-up salon when you've only done make up on your own face... Then saying it is free... Then saying that you've had amazing results. Of course people will then want to excitingly request a reading.
Because of your feelings of worry, the reading will probably go wrong. These attachments cause distortions in the cards, and you will be unable to focus on the reading properly.
For now, stick to solitary readings for yourself until you are comfortable with your ability. Learn a few tarot spreads, and maybe even create a few on your own. More importantly, take your time. Decline the requests, and put your own growth first.
