I got diagnosed and I would like tips from people who have lived with it.

I got diagnosed. It makes a lot of things make sense and fall into place. I always struggled with a lot of the symptoms but it's started getting worse and worse recently and I really need some pointers. I feel so alone all the time. I have a problem with drugs I haven't taken any but my mind is starting to glorify pills and Codeine. I love the idea of studying them but I keep getting violent thoughts about taking them. I lash out all the time. I am a manipulative person regularly. The worst part right now is the paranoia. I have horrible paranoia about this girl I'm talking to and her not loving me back. I'm so hypersexual it's painful sometimes. I have spurts where I'm very egotistical and think I'm the best human alive. I change my mind on what carrer I want daily. I need help with anything. Any tips older people with BPD have learned. I'm so scared I'm going to go crazy and hate my life forever sometimes. I don't like hating myself then loving myself in the same 10 minutes.
