Hello everyone...i am in real financial problem...i am a 25 year old boy who was addicted to gambling since many years....but in last one year i lost my everything...i belonged to a quit rich family...my father and mother both had a job but they both retired and my father passed away in 2018..they had approximate 3,00,000USD in last couple of years...i lost every thing that my mother and father earned in their entire life

You have lost 3,00,000 USD in gambling

You should have known the risk in gambling. This is a big amount and you could have invested this amount in some better business or property and could have gained good money but unfortunately you have lost it all.
I believe you should now have to forget about the past and look for online work through freelancing.
