To people who already work as web designers/developers - help me decide.

Given your current situation I say go for it. What do you have to lose? If your polish your skills and become a ninja at generating markup, the employment opportunities can be very promising. Employers, digital agencies, and design firms are alway looking for people who know code. If your good at something, never do it for free :)

If you work hard enough to learn as much as you can and you genuinely want to succeed then you will be fine and you go for it. And you'll learn whether you genuinely love doing it and are good at it. If not, you can move on to something else, but I suspect you might just be fine :)

Personally, I think there's a really big gap between being a Lead IT Engineer and being an entry level web designer.

You mean my IT background is not good enough? In my country You dont need much knowledge to get promoted, nor You earn high wage so money wise it will be the same or a bit better as web designer if i manage to freelance a bit after work.

Im just wondering if becoming front web developer requires me to be some kind of geek or anyone who tries hard can achieve it.

As a working frontend designer/developer I think it's great you're going after a position that makes you happy. I believe to do it well you will need that passion to succeed. The red flag for me is that you have a few months and then you must land a job with your new skills - that pressure can cause frustration. From what I have seen, many FED jobs require years of experience, portfolio urls and technical interviews, so I would suggest reviewing current job positions now so you know what to expect in 3 months.

I see you already have a good amount of html/css/js points, so you are well on your way to gathering the knowledge needed for building a site in pure html/css/js. What you might not have is the time to apply those new skills to produce original portfolio pieces to show potential employers. Using the Bakin' website to show off your frontend skills won't cut it. Instead, you might want to build a mobile-first personal site with the aid of foundation.zurb.com (.scss) or getbootstrap.com (.less). This should not take too long and it will give you a great understanding of organization, pre-processors and how to think in modules. If you haven't already checkout Frameworks: http://teamtreehouse.com/library/framework-basics

Once you feel comfortable customizing a framework I would start building portfolio pieces as quick as possible, try to have at least 3 different url's showing your design/dev skills. This can be a single page site for a fake app, the front door of a github project you like - showing off logo, branding and typography. Modifying a responsive WP theme can be very beneficial for increasing your design and development skills at the same time. This is all assuming you will need work samples in order to get a job.

Your IT skills will help in the coding, debugging and workflow side of FED but probably work against you on the creative side (right side of the brain). If your job requires that you design pages/screens from scratch (not just framework/theme mods) you will need to get comfortable with building out a design with resources like shutterstock.com, typecast.com etc. You can get great ideas and inspiration from dribbble.com, patterntap.com and the many FED resources online: https://github.com/zedix/frontend-resources

So... I would start with a realistic job description in mind. Focus on producing and using the skills and realize that the learning process will continue for awhile. Especially if you want to be a Unicorn - a mystical creature who can plan a site/app like a UX Architect, design it like a seasoned Visual Designer and build it like Front End Engineer. Not to be confused with a Full Stack Developer.

Go for it! At best you have a new job/career. At worse you try again at a later date.
