I can relate totally to those feelings
I’m very tired and frustrated with being constantly skint.
I did higher education, colleges and universities to try and end up with a decent job
My younger brother who went straight into work is much better off
I, however don’t have a family, and you seem to recognise that they are the world to you, so focus on the positives
And like others have said, you’re half way there admitting these feelings to yourself
