my heart goes out to anyone who is struggling and I just wanted to offer some (maybe helpful) advice that has always served me well. Start locally, think about a need in your community or a community that you have connections with (anything that people need in terms of a service)and start a business offering it (depending on your experience and qualifications in case you need a license… etc. you should obtain all that you need,possibly including unpaid volunteer/intern experience to familiarize yourself with this area or to gain expertise…etc) in case you have no skills/experience in anything…)
Once you have a business idea, reach out to retired businessmen or someone you know who is in business but with whom you will not be in competition and run the idea by him (very important). There are prob. community resources of retired businessmen that can meet with you — where I lived before they had an organization like that, check into it.
Put the word out with everyone you know… especially your Rav, shul, local stores, in other words … network. Invest little and advertise in a local paper — don’t invest a lot of money right away… I’YH if it goes you can then invest whatever you need.
Most importantly: After you do your hishtadlus, daven to Ribbono Shel Olam to give you the parnassa you need so you can live like a mentsch and serve him properly…because if you are worried about parnassa it is exceedingly difficult. Say a kapittel Tehiliim before any phone call, any meeting, anything you do throughout the day. (so says Rav Shlomo Brevda shlita)
Just wanted to share what I have found to be true for myself.
