well I came here to check the answers to my post and found out an amazing thing.
When I posted my message I quickly browsed through the 300+ forums to find appropriate ones, and I chose " Love " and " Law of attraction" forums.
The LOA forum didn't seem much appropriate to me, but I didn't find a better choice, and thought, maybe I will find good advice there.
Well, it ends up that my post does not show on the LOA forum. It is posted on the FORGIVENESS forum instead!
This is quite amazing since I could have posted by mistake on 300+ very wrong forums...but my post ended up in the only place it actually belongs to.
Looks like a message from above!
Thank all of you for your kind answers. I think the trouble is deeper, or else I would not feel this coldness or I would have been able to face the issue from the very start.
The truth is that I always feel coldness from my mom even when she calls me and this event only made that feeling more hurtful and sharp.
I realize my family has issues and I have with them, too. I don't think those issues will solve overnight. But I will call my mother and tell her about this. Or maybe I will just forgive and forget about the whole thing.
