My two cents on your LinkedIn profile:
Try to look at it from the perspective of the employer not knowing anything about you: They are looking for a nice and decent person with enough skills to start the job. And they spent less than a minute, sometimes even far less, at looking at your profile.
I recommend you to choose another photo, one with just you and no other people and with more contrast between you and the background.
And maybe you should also consider to change the image on top. This one gives me the impression that you really dislike Internet Explorer.
But as a web developer you will write software for all browsers. IE is still an important part of that job.
What if an employer can choose between a developer who seems to dislike that task and another one who looks forward to the challenge?
To me it’s not clear what you’re looking for in a job. It looks like a general interest in IT and software development. Which programming languages do you really like? What are you really good at?
Narrow it down a bit in the description and take a critical look at the long lists in the skills section. Are all of them important to mention in those first few seconds when an employer scans this page? Which ones can wait until they’re brought up in an interview?
And I agree with @kevinSmith and @sunnyday90210, it might take time to get a job and there will be employers/people who are not interested in you, as it also happens in all other areas in life. That’s nothing to worry about.
But you also describe studying without support and being alone. I studied without support, that was oké for me. But I really enjoy the meetup groups, Slack groups I joined and forums like this one. People here will help you and you can help others.
I’ve met all kinds of nice and interesting people, both online and in real life and from all over the world.
And the more people get to know you, chances grow that one day someone will mention your name when their company starts looking for a new developer.
Also, as sunnyday90210 mentioned above there are jobs posted in those places, so you might be the first applicant.
And last but not least, get some rest, let it all go for a while, enjoy life and use time to play (real play, or sports, gardening, going to the movies, or whatever you really like to do).
That will help you to relax, to look from a different perspective and to rebuild some self confidence.
Good luck with your study, don’t give up, you’ll be fine, even if the road is a bit long and bumpy.
You’ll get there in the end and you might tell us all about it, so others will learn from you and your journey!
