Sorry man, you had clearly stated in your OP about your family & father
...my bad for getting you to re-hash.
So, what are you going to do, about you? (Outside the shitty, dysfunctional family situation)
Do you go on feeling less-than, or?
How do you cope (a part from using). How do you deal with internalising, your folks mistakes? Should you, even?
Re. Sexual assault, this is a separate issue. Always keep it separate & never confound it with any other issue as it's cancerous. What's happening with you re. getting support for this, you need it, all the time.
...if you're father, is narcissistically, avoiding his responsibility to his kids & spouse & your mom is in denial - being a proverbial, 'doormat'.
This might be what you are identifying as, as it's the more functional, i.e. just choose 'soma' as it's what keeps things functional? There is truth in that, when economic- dependence is imperative - doesn't mean it's right/healthy - you have captured that, with your pain (unfortunately).
Re. Peer-comparison - it's normal, it's competitive - what makes it dysfunctional is not evaluating the comparison correctly i.e. Doing it without respect for your own limitations/strengths & not having a respect for that in others; value judgement, compassion & humour are things to cultivate, in this shitty, rat-race.

Society is cruel, it didn't begin, or end in the 40's & most of it, is wasteful.
Am so sorry you had to deal with parents that hadn't figured out quality of life but put economy my of life, before all.
You have some amazing, insight into the dysfunction (yes, it doesn't fix it, but it's a start toward it, if you can let yourself accept the fact, that it has nothing to do with you)- no doubt you will, come out better to yourself, if you stop berating yourself ( them, also - goes, they deserve it but society is fucking horrifically, cruel & moreso, in decades past, so that, is something to consider, in the maelstrom that they swept you into).
I have no doubt, it will get easier for you, if, you start to treat yourself with the care & respect you deserve - you do deserve it, when you start. Blame them, forgive, forget the past, put yourself first, even if you feel unable - this is living - be.
The crutches are temporary fixes but they will kill you sooner, if you don't deal with using them. My hope for you is to live longer, so you can be at ease with the fruits of life & swipe-away any bs it throws your way. You are clever, you are beautiful & when you realise your own, wisdom by yielding to your human foibles & going through the painful, process of processing them, you will shine, you are in the process, I think?
