feel horrible

when we do thing out of guilt it's often not good. like my mom buying me a dress out of guilt that i couldn't have anything from a donation bin. the 1 thing i feel guilty about is when i walked up to give my sermon i everyone cheered me going up. it was like having a light on during the night. the reason i felt bad was because no one else got it. that embarrassed me and made me feel guilt over it. i was the only 1 who used little to no scriptures (i used principles but no scriptures to "back it up") and didn't have my standard works physically with me (only my app). everyone said they liked it.
