What if you learn all the stroke orders in the wrong order? I started learning Chinese a few months back by myself but stopped as soon as I realized that stroke order was important part of learning the Chinese language
I don't want to go for coaching and want to continue learning
But I don't want to unlearn every thing after I have reached a level of HSK1 or farther
What should I do? 

Is coaching really necessary? If it is I can do that as well. 

I don't want to make mistakes.
You don't need a teacher to learn stroke order properly, you just need to learn the basic rules and make a habit of looking up the stroke order for new characters you learn. This will feel like an additional burden for a while, but you'll soon learn the rules and you will find that you can often guess the right stroke order, even for a character you have never seen before.

If your goal is to write neat, beautiful characters, then you do need input from a human, but to learn basic handwriting and stroke order, you don't have to have a teacher, as long as you look things up.

Some suggested resources:


Pleco or Hanping for looking things up on your phone
ArchChinese or MDBG for looking things up in your webb browser
Looking things up in printed books is a pain, especially if you're a beginner
Many apps teach you stroke order: Skritter, Pleco, TOFU learn.


Stroke order might feel like a big hurdle for you at the moment, but it really isn't that hard. Compared to learning any other aspect of Chinese; stroke order will only end up taking up a very small proportion of the time you invest. Just look things up as you learn new characters and after learning a few hundred characters, you'll wonder why you thought it was so intimidating when you first started out.
