Breakfast

Usually,I skip (don't eat) breakfast,because I always sleep late and get up late, therefore/so lunch is my first meal of the (a) day. (But) Today, however, I got up at 8,then (I) ran on the treadmill for 20 minutes (miniutes) in an effort to lose weight, as (because) Summer is coming/just around the corner. After a shower, I started to learn (learning) English. Come (without eating breakfast too.when at) 11AM,I was feeling (became) very hungry, but (I) couldn't find anything to eat when I opened the (my) fridge door. (frige). So sad! Tomorrow morning will be the same, because I was too busy to buy (some) bread.What should I do?

It is common to say 'skip' if you miss a meal. In English, you should not start a sentence with a conjunction in a formal essay - so best not to use 'but', 'because' 'and' - these are for linking two or more phrases within a sentence. It is by no means definite that running on a treadmill will lead to you losing weight (maybe not eating breakfast will, though...haha) so it is better to say 'in an effort to lose weight'. You need to eat, Demi, so I would suggest popping out to buy a loaf at 8am before you exercise.Good luck with everything.
