What's an average payment per month for SSDI, and do you lose your Social Security?

Oops - hit send by accident. So - somewhere in the mid 60's - mid 70's. SSI can be very difficult to qualify for unless one is profoundly disabled - just having a bad back or chronic fatigue syndrome often won't qualify as the government will expect

SSI is for low income, disabled individuals. Someone under 18 can get SSI if they are disabled and the parents are low income. Once the individual turns 18 they may receive SSI if they are disabled, unable to work, and have no real assets. SS is for individuals who have worked, paid into SS and are of legal retirement age - not sure what that is these days - somewhere in the mid 60'

long story. very specific field, not a field actually a niche we created. biz partner screwed me over. Lost everything and now no one wants to train me for something new. thinking im too old especially when they realize what my income was. Believe me, Its been a long depressing long story. so much so I am on antidepressants, suffer from migraines, insomnia, panic attacks. it has ruined me.

when you retire? and I don't believe you can't get work at 54; know too many people who are, so...

I understand about the ones that I had not paid into the system but for the ones I did. I havent worked cant get work im 54 now. cant I get what I did pay into it?
Or do I have to be disabled.

SSI is not dependent on age, so it's not a matter of how long or not it's been since you worked, but you can't get actual Social Security for jobs not paying into the system; concerned about my son in that regard

when can you collect SSI? (at what age) Can I still get mine even if I have not worked in over ten years now. I had worked for 30 years prior to that but sometimes as an independent not paying into the system.

Once you begin receiving retirement you cannot also receive disability. You get one or the other.

One can collect SSI with retirement, if the recipient receives very little retirement and has under $2,000 in assets.

Average won't help you. Payments are based on what you paid into the system over the years. The main difference between Social Security Disability (SSD, or SSDI) and Supplemental Security Income (SSI) is the fact that SSD is available to workers who have accumulated a sufficient number of work credits, while SSI disability benefits are available to low-income individuals.
If you are thinking you will get double benefits, the answer is NO
