are you sure that you always did your proper hishtadlus? when it came to finding a shidduch or a job before giving up? how many years were you working on it before stopping? 5 10 or 20 years or more? a person should NEVER give up his hope for success & help directly from Hashem forever until he is niftar. That would mean still looking for a job & a shidduch. Why did you stop? nothing is impossible. I know many people who have gotten married first time in their 50’s or 60’s etc… & many people who have found jobs that can work for them even in their 70’s so they can make ends meet & also keep a daily schedule etc…
start to work on yourself, by looking for a job that is in your league for your age now & speak to some shadchanim with your resume updated to today’s information etc….
