You need to know that this particular section of the forum does have a lot of posters who are actively looking to trip you up, to find fault with you, to pick apart and twist what you're saying.
It may be better to report your own thread (bottom of your first post there is a 'report' option, hit that, pick 'other' and write in there) - and ask MN to move your post to a more appropriate section of the forum.
I think it is quite clear you recognise you have some problems you need to solve, you're keen and willing to do that.
As hard as it is, you have to let go of needing the approval and praise from your parents/siblings.
We all want that, it is the default setting for humans to want that from others, particularly our relatives and especially our parents.
Some of us will absolutely break ourselves, physically and mentally, trying to get it from people who are not capable of giving it.
I would strongly recommend you seek some counselling to help with that, it will help you step away from your family which I do think is what you need to do in order to move on with your life.
Don't think of this as proving to them that you're good, you're worthy etc... you need to prove to yourself these things, it is after all, your opinion and to some extent, the opinion of your true friends, that actually matters.
Your parents and family are simply people you are genetically linked to - it doesn't automatically mean they have your best interests at heart, that they're the best people to advise you or that their opinions matter.
