I have felt much more separate from the world in recent years, since I lost the two people closest to me, and sometimes
I believe I know why I have these thoughts though: because my closest loved ones from whom I wished never to be separated are on the proverbial other side; because my connections here since have not as yet come to represent the same potency of connection, and so it's logical that some part of me would wish to be wherever my loved ones might indeed be. I honor what the thoughts represent, and think of them as signals to tell me that I need both to deal with my innermost feelings and to enrich my waking life, so that the feelings needn't become buried and dangerous.

I don't know if this will constitute a helpful suggestion for you, or if I am just stating the annoyingly obvious, but if you can sort out what feelings may be causing the thoughts, you can work on the feelings. That's what has worked for me anyway. I still have the thoughts, but not as often, and when I do I just sort of thank them or acknowledge them for showing themselves to me, expressing to me what needs to be expressed, so that I can know the opportunity to address my feelings, and I feel more at peace with their existence through being connected with understanding of what they represent.

I even think of deeper feelings of depersonalization or derealization that I've had as being natural, since each of us is borne of greater spiritual reality than our commercialized lives pay fair homage to. But that's just how I go about things.. I feel like it's best to work towards being able to lovingly acknowledge and accept every part of our selves, and to accept the dignity of our uniqueness.

As I also honor the uniqueness of your journey.
