I'm not in my 40s (in my 20s actually) and currently have no full-time job either. My sole income, for now, are all from my freelance gigs which isn't much. Even that gave me anxiety and sleepless nights every now and then. For the most part the only available jobs here are sales jobs from insurance and dropship products.

Not sure if my situation is any different if I were to go West Malaysia/KL but I have a feeling it won't.

Coming back to your case... Like how a lot of ppl here say. Try sell insurance or bank products? Or can consider doing grad driver, grab food driver, food panda jobs? Those are the only jobs that are "actively hiring" for now. Knew a couple of ex-uni friends who can't find a job even graduating from MAs so decided to go be grab drivers (KL/West Malaysia based). Worst come to worst, probably try fast-food chains and be their service crew. Not the best jobs but if they are willing to take you on and give you a job, it's better than nothing.
