You’re talking about a personal level though, which is different to what you took up arms against here: Discussing Retroactive Magick by derailing a topic someone made thanking me for stuff. 
I don’t do magick to alter my own past “mistakes,” me (and my old man) are doing work, ongoing, to change wider issues. And that is really all I have to say on this.
While I am the last person to mock people for taking voices in their head seriously, I question how much you have studied time and perception, the Kybalion, and so on?
Also since you originally addressed this specifically TO me, calling me “grossly irresponsible” & “stupid and immoral” and then flinging out “chalatan” as well, I would like to point out that I do not, and never have offered paid magickal services, not even for “donations” or gifts, so how I can be a charlatan when I refuse to take on personal cases, and refuse any kind of material or other recompense, is frankly beyond me. 
I am addressing this because this is how rumours start - a mention that goes unaddressed, an assumption that gets taken on by others who are newer to the forum, etc.
if you wish to do a little framing around this topic, pick your sitter with more care.
I can send you a series of tutorials for core shamanism which will permit you some degree of closure perhaps, if you learn the method and are willing to communicate with their Higher Self.
I did this when one of my parents died, and it was an immense blessing.
