Is hydrogen bonding considered a dipole-dipole interaction, or is it different?

It's considered a type of dipole-dipole interaction but it is stronger than the normal dipole-dipole interaction.

Hydrogen bonding is a special type of Dipole-Dipole as it is considered stronger than a regular dipole-dipole force.

Because Hydrogen bonding is between a hydrogen atom (which is partially positive) and either a fluoride, oxygen, or nitrogen atom (which are partially negative) and the difference in electronegativity is more significant than most dipole-dipole interactions, a hydrogen bonds are typically stronger than most dipole-dipole interactions due to the high polarity of the bond(s).

Yes, and since hydrogen is much less electronegative than oxygen, nitrogen, and fluorine, the dipole is stronger.

It is a special type of dipole- dipole interaction, but it is a slightly stronger bond. Hydrogen bonds are around -15kJ/mol and normal dipole dipole interactions are about -2kJ/mol
