Got laidoff , have experience in Java , do we have any group to prepare or get help ?

I have around 5.10 years of experience , within that 2 years went in bench it self and most of my projects are maintainance . I worked barely 4 years excluding bench and in that I worked 6 months on development and remaining 3.5 years I am in maintainence projects only. Recently I got laid off I am lagging at confidence levels , skills particularly which I didn't worked in projects - multithreading , spring security , microservices . I am trying to ask is , is there any groups of any medium to help each other , preparing for next company ?
