I totally understand you. Sorry to hear that your friends not really are true.
I've surrounded myself with people, who didn't wish me well. I've trusted and helped them financially, I thought I had true friends, but at the bottom line I've got known that I just been used...
I was asking for help with my mental problems and sharing very personal things for last few months with 2 most closest persons. But at some point I've found out that it was just a fun for them. They made chat group in WhatsApp , and were dumping there everything I shared, having great time and huge discussion.
When I saw that, I couldn't believe how mean and cruel people can be...and I'm not talking about strangers, I knew that people for years...
Your mother - it's different, I'm really sorry to hear that person don't care when her child saying about CTB...
