Dealing with long time unemployment

I suffered from depression during the only job I held for about 2 years in the last 5 years. I didn't perform well, and now with my 3-year employment gap and lack of achievements, no one is willing to even acknowledge my applications. I tried governmental employment services and all they did was editing my resume and cover letter but didn't change anything in reality. I went to a recruiting agency and the recruiter told me I have no "industrial experience", so I didn't see him again. I reached out to the people I know for any leads, and they all ignored me or just told me to tailor my resume to the job description!! I contacted my academic supervisor and made him aware of my situation, but he also ignored me probably because I am the only one who is unemployed from his graduate students, and he thought I should find a job myself. It's really hard to deal with unemployment and for not being independent financially. I admit I was depressed while holding a job, but not having a job makes depression 1000x worse, and it destroys confidence big time. Some people suggested freelancing, but even in freelancing they need experience and you have to have good profile to get paid reasonably. Besides it seems too much work for me now with my lack of motivation and energy to set up an account, and write a good profile and pitch my proposals
