Sorry about all the bad things that had happened to you, mate. But our destiny all depends on our actions. You have posted all your lessons that you have learned in your previous wrongdoings. Life is also unpredictable, but if we tend to fight and had a courage to stand up again, then we will survive and move on.
January ... lost my tooth went to dentist ,she should have fix it ,payed money still didn't heard from her not even now
February... pandemic started
March ... lost my job
April ... Girlfriend dumped me for good do to fact i am poor and she was only interested in money
May - June ... Lost all my savings at the casinos after lockdown do to fact i entered a depression
All those struggles and problems has all the answers. If you lose your job because of pandemic, then find a new way how to survive. If your gf dumped you because of your unstable job, then you dont deserve her. You have family to lean on. And lastly, depression will make your life worst if you dont fight it. Just like what happen, to you. Hope you'll get better and start all over again.
