I lost everything and am alone in life, I'm in my early 60s. I have money and it matters little, I can't even find people to help me spend it.

the difference is your are still very young and can rebuild. My suggestion to you is that you immediately begin trying to build any relationships. Start now it is far from to late for a 29 year old. Recontact anyone from high school or college or anyone you loved or clicked with. Work to maintain your relationships, and don't forsake people. Start now to build new ones, and really work at it. Join clubs, get outside, start a social calendar, meet people to eat meals with. Start a group of guys that Bowl or play cards or bike or just walk once a week or month.

I am now alone because my grief and rage push everyone away. People don't generally try hard enough to get through to a depressed or grieving person. They respond to the first rejection and walk away.

It far from over for a 29 year old. If you have to try an SSRI. And build medical relationships now as well, try to find a Doctor or Drs. your own age you have a real relationship with that can build over decades and help take care of you. I've been bounced around all my life and currently have no support and lost my Dr. again during 2020. They want anyone over 60 dead, so life is just a jumble of grief and loss and suicidal feelings.

Learn now not to be the turd in the punch bowl everywhere. Fake it. Take Anti depressants. Do whatever to build a life, don't let it fade away in front of the PC like I did the past 20 years, posting on GLP and the Velvet Rope and being summarily ignored and banned until I wanted to die. Go where there are good people and bond with them. Get out and live while you are young. Now in my early 60s, I see almost no reason to go on.
