new to biking. my commute is only a mile and a half one-way and yet when I get there my legs feel shaky and weak. riding back home, I'm okay. is this just cuz' I don't eat in the morning? is fuel really that important, and I'm a stupid beta cuck? should I cry and piss my pants?

p.s what do y'all eat in the mornings? I'm not fucking anorexic I just don't like tasting things in the morning and waking up earlier to cook/prepare said things.
