His advice is probably the best in the thread, everything else like 'build a bunch of projects' or 'study leetcode every day' is going to lead you to 6 years unemployment unless you're one of the few highly self-motivated, which you're not, given you've been able to go 4 years unemployed already. At least a job gets you waking up at consistent times every day and people to talk to. You could try gatehouse security or help-desk and try to do the leetcode stuff on the job while you earn, then eventually get back into tech.
