I do not know how to advice, but I would say I am also in same boat as you. Because I believe a lot of out there is also jobless ( this including myself) but one thing I only could advice, start to learn new thing or skill.
Try put more focus on doing something, I have tried it does help me and give me sense of purpose. I can understand what you feeling right now because I am also have being felt it since the Covid start to hit at our country.

If you have a friend or person you trust and willing to talk with, go and talk (either through phone, video call, chat, forum). For me I manage to attend some training course or seminar and it does help to make me feel happy talking to someone new instead or family.

If you would like to learn new thing, you could go to elatih web site. this is government initiative for Malaysian citizen to upskill and reskill. I also have use it to learn new skill.

Well hope a bit of my advice and opinion will help you. Believe me you are not alone. And keep on trying to find a way out from current situation. I hope you will find success and answer to all your problem.

elatih I not sure about the certification. But is elatih is like a platform for a collection of the other professional course that allowed you to attend and learn. I used it to my additional note and lab test for my Certified Associate of Python Programming but the course syllabus is by Microsoft.
