It's tough to draw boundaries for me too but I am trying. INFP here, it's not easy for us sensitive introvert types sometimes online or irl I think. We express ourselves openly and honestly and some people are just thoughtless or excessively aggressive or harsh, it can be tricky not to internalize for me sometimes which rationally I know is dumb, some people act like jerks for no reason online other than the fact that they can. Glad you have found your feet and stay strong in believing in yourself! ❤️👌
