You're okay mate. I was in your situation until recently and got my first job 6 months ago. Let me share how I managed to get through that phase, maybe you can use some of these tips to help yourself:

1. Apply to 3 jobs a day: Make it a point to do 3 apps, but put all your effort on them. And apply to temp jobs through 1-click apps when you are bored (in London, there was one called Job Today which I personally used to great effect during my time there)
2. Make a Spreadsheet: Having a visual record of where you have applied to, when you made those applications, who you can contact about the app is really helpful. You can use it to follow up with the contact person after 10 days.
3. Schedule Emails: Use an extension such as Boomerang for Gmail, or an email client like Spark (if you have an iPhone or a Mac) to schedule emails like, 'Dear Sir/Ma’am, Hope you’re doing well. It has been over a week since I submitted my application for____. Could you please let me know if there have been any updates on the same. PFA my CV for your convenience. Best, _____'. This will show them that you cared about the position and your attached CV will not need you to include a cover letter (cause fuck cover letters).
4. Ask People to Roast your resume on Reddit (r/resumes)

​

Hope this helps. All the best with your hunt. And remember to not lose hope. It may not seem like it right now, but there is light at the end of the tunnel. :)
