Wow thank you so much for all your great replies! It never stops to amaze me that sharing fears and having them validated and seeing that we all have them makes me feel immediately better!
Need to keep practicing
I understand life happens and (although unlikely) my T can indeed die. The thing is, my relationship with him is pretty much the first honest and deep relationship I've ever had (sad and depressing i know) so I'm not as optimistic about getting over him and finding someone else to try again. I don't want to. Hopefully nothing will happen.
I've been thinking about what you said, that maybe it's related to some sort of loss in my past. No one meaningful to me died when I was younger, but when i was on my early teens my father had a severe heart stroke and nearly died (spend several weeks in ICU). Ever since I've always been worried that my father can die all of a sudden. For example, whenever i have a missed call from my sister (she doesn't call much) i get really anxious, my first thought is always "oh god maybe something happened to dad" and I can't go through the day without calling back and asking my sister why she called.
I understand now that I've always bottled up all my fears and never spoke about it to anyone (actually i don't even remember crying when my father had a stroke, or showing any emotion at all other than feeling sick everytime i tried to eat) so I've always assumed the event never had any effect on me.
Mmm you gave me lots of food for thought here.
