I’m sorry for your loss. I can sympathize with you because I lost one of my best friends years ago.
From the years of counseling I’ve participated in, I’ve learned that people experience grief in different ways. There really isn’t a better or right sequence to experience the loss of someone. You’ll go through it as you see the need to or feel.
Denial, Anger, Bargaining, Depression and Acceptance are the most common. Again, these don’t have to happen in this sequence. You might experience that you jump around as time goes on, and that’s perfectly normal.
Now talking about how your possible untreated ADHD symptoms might be negatively affecting you. I have been officially diagnosed with ADHD and have experienced the loss of a best friend to suicide. One of the perks of having a ADHD brain, is that you can think about a large number of things in a given moment. But this can make you feel totally stuck and overwhelmed if you’re going through grief. The best things to do I found during my experience and some advice from trusted people, was to allow for myself to spend time to process what had happened. It’s important to reach out to others to talk about how you feel or how you’re doing. Remember that you’re not alone in experiencing grief of the death of a friend. Reach out to someone that you can trust that is going through the same event as you. This can help you feel like you’re not alone in your experience of grief, struggle(s), loneliness, etc.
It helped me very much to talk to a counselor that I knew and could feel comfortable sharing these deeper feelings and events with. If you can’t find a counselor, seek out someone close to you that would be willing and able to listen, support you and suggest options to help you through the process of going through grief.
Feel free to message me if you have a need to talk. I don’t mind talking about the harder things in life most often. And last but not least… This Too Shall Pass.
