For every sin, do i need to go to a priest for repentance?

I have found it difficult to always go for Holy Communion after examining my conscience and find that i sin every hour through my words, thought and deeds. i am not in position to see a priest every hour, therefore i fear to go for Holy communion with ever my dirty lips.

We only are obligated to confess prior to communion if we are guilty of a mortal sin.

However, these are some cases in which Holy Communion may be received without fasting.

(a) Venial sin does not make us unworthy of receiving Holy Communion…
