I blocked everyone from my life

I asked my close friend for advice on something & she went to go snitch to everyone, it was a sensitive subject, and it was about my bf, and he’s pissed... I blocked literally everyone, I’m done, I’ve been going through so much shit, so much crap, I deleted everything, Facebook, IG, Snapchat, blocked everyone... on my phone as well. I hate myself for thinking I could genuinely trust someone... I hate myself so much... I feel lost & idk what to do anymore... this is only my second relationship & I needed some advice...
