Hey!
I understand how difficult it is for you to mentally deal with this feeling.
Lets take this symptoms down to a deeper level. From what you have mentioned, feeling of someone committing Suicide or someone dying is a fear, fear of losing them. And as you correctly mentioned, you remember a episode from your early childhood experiences when you had a similar feeling. There has been some trigger ( you may or may not be consciously aware of) which leads to this feeling of Loosing maybe.
You can get in touch with me, in this case Psychotherapy, Hypnotherapy, Art therapy and an integrative approach can help you!
Next Steps
1. On a sheet of paper write everything that you fear losing ( People, place or anything that comes to your mind)
2. Write down strategies that will help you if you lose them.
This process will help you to reduce your anxiety.
