Breaking down from within

I'm from a tier 1 college, and then have experience of almost 4 yrs and a java backend developer. I have good product based brand names and one big mnc too in my resume. I have been without job since last month where I got laid off from my role. Not even getting calls. People with less experience are switching left and right. I was getting few calls even when I was not applying around august last year. I'm very tensed at this point, i have no friends too. All by myself thinking and wandering what's gonna happen. I worked very hard to reach here, and then facing this. Not even a single call in last 15 days after applying to 100s of jobs even fresher roles I'm applying at this point because I don't feel nice sitting at home like this and same response there too. What is happening?
