This was my day

Today I got up at 7 a.m. and I had my breakfast [could also say "ate my breakfast"].  After that, I went to church to pray for a moment ["one" here isn't technically wrong but it's more common to hear "a" in this sense].  I came back to my house and I helped my mother, you know, like some household [things/chores]: [a] leaking pipe, no electricity.  Yeah.  After that I watched some videos about music, took a shower ["I" not needed here since you've already asserted that you're speaking about yourself but, again, not incorrect], and [I] working on my computer all afternoon because now that I don't go to university ["college" is more common here in the states, "university" pretty much everywhere else as far as I'm aware], I have vacations for 2 months but I still like to study some things that I find interesting.  Well, that's ["that is"] my day.  Thank you.

You're English is quite good.  I hope I kept enough of your voice (the way you speak) in my correction and that my notes make sense.  The only big [important] note that I have is your comma (",") placement; it comes directly after the last letter in a word rather than before the first letter of the next one or with spaces on either side.  It seems like at your level your biggest work is getting used to colloquialisms (how certain concepts are phrased in certain regions) and expressions.  Keep it up!

Note 1: This sentence would probably be better if you use "break" instead of "vacation". Vacations can be long, but when talking about school, most people use the word break. Ex. Summer Break, Spring Break, Winter Break. If vacation is the word you are trying to use then try changing the start of the sentence to "Now that I don't go to a university anymore, I am on a 2 month vacation." Notice instead of "having" a vacation, you instead "are on" a vacation. So I use "I am on" not "I have". Think of it like "I am on a trip". You would not say "I have a trip".
