It doesn't have to be forever, especially if you are younger. I am 58 and my husband retired, so I sort of gave up and filed. My "people" from SSDI did ask if this was all my doctor's idea or mine. It was my doctor's. I did have a lawyer but was approved in a few months so didn't need them (but I would highly recommend one).
It was VERY hard for me to feel "disabled". My t and I are working on this very label right now. I am 58 so I tell people I am "early retired" to be with my husband who retired and is now working from home. No one asks if I am on disability. I am a bit ashamed of it, tbh. BUT this does not mean anyone else should be. If you need it, you do.
