There are many people who are being abused on a daily basis who don’t even realise it. When other people mention abuse, these people imagine the horrors of sexual and other physical forms of abuse, but it’s most pernicious form is psychological abuse. A large number of the people being psychologically abused think that either it is normal, or it is their fault, or they deserve it.
It is not normal for the people close to you to put you down, to undermine you, to attack you verbally or in any other way. It should not be normal for people in your wider circle to do so either. If they do this it is NOT because of you, it IS because of them. They have a problem, rather than dealing with that problem they are going to punish you.
Additionally, anyone who seeks to isolate and/or control you is abusing you. People who love you will support you and encourage you to live your own life as far as their self-confidence allows them to.
No one deserves to be undermined or abused in any way. But we all have to take responsibility for our own problems and actions, we need to be brave enough to reach out to other people when we need help. It is a very strong thing to do, to reach out and ask when you realise that you can’t solve your problems alone.
I wish you all that strength in those moments of self doubt, we are social animals, we are stronger together when we support each other. Jealousy and fear are what make us weak.
