Thank you for taking time for me. I am really grateful.
This can help me I know but I don't know how to use technique for my situation.
Below are some of my previous replies which were posted late, because I am new to this forum. Please read if you didn't read them before.

"I go for morning walk as well to keep my mind fresh. I am taking 7 to 8 hours of sleep and it is enough for me, I don't feel lazy or tired. But the moment I start writing something, my mind starts giving me signals that I need rest, I should sleep. Yes, whenever I start doing mental work, i feel sleepy. This is the reason I started taking Modafinil.

One more thing. I am not a confident person. This is the reason I always offer my clients free sample work, and when they agree to it I feel good about it. I feel like, if I did good once doesn't mean I will do good again.
I know anyone I work with really likes my work on first place and when they give me a project I try to sneak."

I am never a confident person. I want to start working on my own websites and I know that with continuous effort and hard work I will be able to earn more, but then I think what if it never happens, what if my this idea will never work, still I do try to work because there is no way I can give up. I have to keep struggling because I need money to survive.

I think I was like this as a child and in my school. This is the reason I never got good grades but I feel surprised that my concepts in physics and maths are still clear after a long time.

Now, writing as a freelancer and working on my own projects, are two different things. But, when I think about writing, the thought of doing work for my own website disturbs and vice versa. In the end I do nothing except regret. This regret kills me daily, I feel like I can't do anything.

Recently 2 of my Orders were cancelled because they were late, I gave my clients some excuses and they didn't mind. One of the client was so nice that he asked me to do his work when ever i will feel better.

another thing. If I have to write 10 articles on a single topic, I get stuck, I continuously think how can I write on same topic again and again, I run out of ideas and words before even starting to write. Some more clients are approaching me for work and I really want to do this time because I really need money, I don't want that paralyzing thing to happen again.
