I went to the ESL class for the first time 2 months ago.

I often <s>have </s>finish<s>ed</s> my work late. I can only go there twice a week, but my consciousness considerably changed <s>than before.</s> since then.

I was afraid to make mistakes, I could not readily speak, but now I don't care as much.

It's OK to use broken English. First of all, I try to take time and speak with locals as much as possible.

Also, I keep <s>to make</s> a journal in English then I <s>am doing</s> upload it to "italki". There, somebody can correct it. <s>then it will make someone correction.</s>

When I <s>spend</s> live my daily life, I <s>be</s>came to think <s>that </s>about how can I speak in English.

If there are local<s>s on the</s> email addresses, I <s>became to</s> put <s>on the</s> sentences made in English.

I will take a lot of time to change to English. I have long way to go, but I never give up and keep going.

Final product:

Very good! These are some pointers to make it more understandable. ☺️

Understandable, but you could make it better by adding this.

This is my first experience <s>in</s> writing anything about myself.

This sounds absolutely amazing! Here are some corrections if you want it to sound a little more natural.

My life has changed a lot in the past 6 months. I graduated from college last year (August 10th). Then, I got my first teaching job a few months later. This was when I started feeling hopeful that my life would change positively. I knew it would happen, but I wanted it to happen as fast as I wanted. I also <s>have</s> lost 5kg, I couldn't <s>not</s> believe when I noticed. <s>that.</s> I am so proud of myself.

Great job!
