tToday is a very sad day for me,. I am looking back on my life. Today is a very sad day for me. I am looking back on my life.

Always put a capitalised letter at the start of a sentence, and i sounds better in two difference sentences in my opinion.

tToday is a very sad day for me, I am as I looking back on my life. Today is a very sad day for me as I look back on my life.

I am alone in my house, my daughter leavedft, she no longer lives with me, she preferred. She chose to go with her father, and a part of me left with her, this for me is very sadpainful for me. I am alone in my house, my daughter left, she no longer lives with me. She chose to go with her father, and a part of me left with her, this is very painful for me.

I just changed the punctuation in a way that makes a bit more sense, and changed the word order at the end. I also replaced "sad" for "painful" which is a stronger way to express grief and sadness. Also, the biggest pain for english learners it seems...irregular verbs the past perfect of "to leave" is "left" and not "leaved"

I am alone in my house, as my daughter leavehas left and she no longer lives with me, s. She preferred to go with her father, a. A part of me left with her, this and for me this is very sad.

Sometimes I go into her room and I feel cold. Sometimes I cry for her, I miss her, I feel like I'm in a hole but in every moment deep breath and think. All of this is momentary.

So a lot of things to unpack here. First of all capitalised letters and changed the punctuation a bit for clarity. Then i replaced "enter" with "go into" which sounds a bit more natural in my opinion and i also removed "all" for the same reason. Then in order to make a comparison "you feel LIKE a hole" you need to put...well the word "like" so i changed that a bit in order to get a comparison.

sSometimes, I enter her room and I feel all cold, s. Sometimes I cry for she,r as I miss her,. I feeling in hole but a vacuum every moment but I take a deep breath and thik, Ank - all this is momentary. Sometimes, I enter her room and I feel all cold. Sometimes I cry for her as I miss her.

tThe sadness will paseds and I pray for feeling very wellto be better soon. The sadness will pass and I pray to be better soon.

I put the noun "sadness" instead of the adjective, and changed your wish at the end for the sake of sounding more natural. Finally since you used "will" the verb "pass" can't be used in it's past for, but in it's base form (I'm not sure that's how it's called but oh well)

tThe sadness will paseds and I pray for feeling very well.I will feel better soon. The sadness will pass and I pray I will feel better soon.
