It's not supposed to be hard. It's supposed to feel good, and you are supposed to trust.
By the questions that you are asking, it seems as though you are very attached and are trying to move things along.
There was a post by Colonel Roosevelt on Veronica's forum that might help (below), but there is a great deal of resistance that most people on here are trying to overcome because of their own emotional state. You are literally supposed to do the techniques and then go about your life. People are so busy questioning and doubting that they end up building hurdles for themselves.
I've told people so many times to focus on healing themselves first. It's so hard to deliberately put these exercises into practice when the heartache, sadness, fear, and depression are basically in control. Hell, maybe they wouldn't even need to do these LoA exercises if they released the heartache first.
But very few listen. It's like they don't want to heal or take care of themselves first, they just want to jump right into this stuff for a quick fix. They pretend that the negative feelings don't exist and just pretend to be happy as if they are in another universe. A month passes, three months, a year, several years...those negative feelings are still there boiling beneath the surface. That's why I'm not a big fan of the multiple universes idea. People think they can just bypass all the negative feelings they have by entering another universe. That's denial. And what happens when you enter this other universe where everything is perfect? Your subconscious feelings won't accept it because they are still in control, so this universe just stays the same because change has to start within first.
I have a theory that unresolved fear and sadness from heartache and depression could be secretly ruling our subconscious, thus all the clingy and desperate posts we see across the forums. Sure, we could just consciously change our focus and maybe we'd see results...but it doesn't change what's going on beneath the surface. We mask these subconscious feelings with the cover of positive thinking, but it's all still there, powerful as ever. So then we need to also release these stuck feelings, challenge them, face them, outgrow them, accept them, bring them into awareness. That's what healing ourselves from heartbreak is about. But I see people are too scared to accept their own fears, it's as if they think LoA teaches them to shove their feelings away and put a smiley sticker on it. That's not healthy. So then they do LoA exercises in heartbreak mode, the sad state of mind just stays in place. It's like FDR said, we have nothing to fear but fear itself, and people here are too scared to even acknowledge that they have fears, thus fear is still in control.
I've tried the whole "focus on something positive when you feel fear and doubt" thing and I realized I was getting nowhere with it. The resistance was still there, ruling me from within, and I was ignoring it. That's why if you've ever read Larry Crane's "Love Yourself", it says to say "Yes" to all of your negative feelings, accepting them helps us heal, it's not about "ignoring current reality", it's about radical acceptance (the opposite of resistance). Buddhism preaches something similar. A lot of LoA advice I read here either rejects this or never talks about it.
