Hi Op
My advice is know your own worth, if you have any self esteem issues, for e.g cause you have unfortunately experincing shit childhood experinces in any way, (like I have,brought up in children's homes ect,
I would definitely look into good effective therapy to address issues of this nature ,
Have boundaries put into place,
First of all know what your values are,
What you will accept and definitely will not accept in all kinds of relationships, (work/family ect
(I am not just talking about romantic relationships kind,
It's obviously easier if you can cut them off effectively, (act as if they no longer exist,
But if its a toxic working environment or Shit next-door neighbour/crap Landlord
It's obviously by very nature more tricker to navigate,
there's when need of effective personal boundaries comes into place, until you can put yourself in a better position, for e.g a Crap toxic Landlord situations, find out your rights if you are tenant, organisations out there/Internet can help in that regard, in meantime can be on look out ,for better accommodation ect
I just had a good idea 💡 that would really help you, on youtube, there is a really good very switched on motivational speaker, who I often listen to, her name is Cassandra Mack
She does exactly what you looking for here, and so much more,
I very highly recommend her, I really wished I discover her a long time ago,
