Bu sabah uyandım için okul cünkü hissetiliyordum tembel.

I didn´t wake up for class this morning because I was felleing lazy. Thank you

 We don´t use "tembel hissetmek" in Turkish. We say "yorgun hissediyorum [ I feel tired ] even if we don´t and feel lazy. We always use excuses. 

Gokuyum . Thank you

And how do you say "dont be lazy"? Yorgun olma ?

 You haven´t understood my post. I said there was not such a thing "tembel hissetmek" not "tembel". Even we can say "I feel lazy because I get low grades". But "feeling lazy" in this context isn´t same with the "feeling lazy" in Polyglot´s sentence. Context is really important. Have a nice day.

 Maybe "tembelliğim tuttu" can correspond to "I was feeling lazy".

Bu sabah tembelliğim tuttu okula gitmek için kalkmadım.

I don´t know.Just a suggestion.

 It doesn´t sound right to me "Bugün (kendimi) tembel hissediyorum. [ I feel lazy today.] I have never said a sentence like this in my life. Maybe some people says so, i don´t know. We say "canım bugün hiçbir şey yapmak istemiyor" [ My heart (soul) doesn´t want to do anything today]instead of "i feel lazy"

 You didn´t get me. Mine was just a suggestion. After all we have an idiom: "tembelliği tutmak" and it has a similar meaning with "feeling lazy".

  "canım bugün hiçbir şey yapmak istemiyor" may also mean something else other than "I feel lazy".

I think the best Turkish translation for "I feel lazy today" is " bugün tembelliğim üzerimde", not "canım bugün hiçbir şey yapmak istemiyor" 

Yet another suggestion. I don´t know.

I think the best Turkish translation for "I feel lazy today" is " bugün tembelliğim üzerimde"

I agree.

I think "tembelliğim tuttu" fits here as well as "bugün tembelliğim üzerimde"
