From my experience, I'd say, it's not the question of how many months you two have been away. You said you know LOA and aren't new to it. So, I presume you do know this thing - time and distant don't play a role in LOA at all. It's your application that matters.

You yourself have said that you just do something like 5 minutes and then are in an off mood. Tell me, how much would those 5 minutes help if the entire day would be spent in negative thoughts. I am sure, with such a disturbed mindset, you might not be even able to meditate/visualize properly. So, practically, those 5 minutes aren't working for you at all, because you aren't working correctly in those 5 minutes.

For seasoned campaigners, even 5 minutes would be enough with intense feelings. But if you are looking at things in a sad and annoying mood, this is not going to take you anywhere, really sorry to say this.

Come out with positive vibes. And most importantly, learn to live for yourself. I am also more or less going through the same emotions as you, but as you said, you read and learnt things, you still have to learn to love and be yourself. I guess I am doing that for myself, so I don't have those many negative feelings now. I hope you too will reach that level.

I hope thins helps you  And good luck
