Your English is good.  There are only a few grammatical errors in your composition.  Nevertheless, it’s easy to understand.  Here is another way to write it.

It’s been a long time since I’ve been here.  I’m sorry for not greeting all of you, my dear friends.  I really feel guilty for not writing anything here.  I should write a composition every day, but I broke my promise.  The truth is that I’m lazy.  I should be true to myself and stick to what I promised.  However, sometimes my mind plays tricks on me and this is what happens.  Maybe you don’t get what I’m saying but I don’t want to talk about it anymore.  Maybe I’m just going crazy and being silly.   Yep, I just write down what’s on my mind.

We use the idiom “long time, no see” but the wording never changes.

Another common expression is to be "going crazy."
