8 of cups and 5 of cups scream loneliness to me, 5 of cups gives me a feeling of mental illness too though. Then I think of the guy in the 8 of cups as someone who got too full of himself, cheated on his wife with hookers and spent all their money on drugs. Now he's divorced and his kids refuse to see him, he's poor, and now there's a huge sense of regret. Neither of those feeling are really what I'm trying to find, I may be over thinking the cards but I'm justy looking for a card that represents not having a close friendship. Iv recently moved and I'm finding it difficult to create any friendships. Iv decided to do a law of attraction spread, where you choose a card that represents the current situation and another to represent what you want the outcome to be. Then the rest of the spread gives you the steps to get from point a to point b. I just can't find the right card though
I'm just looking through my deck, it's not a deck I've used for years to be honest but your question has got me curious about the cards and I'm leaning towards the 5 of Cups to represent your situation..
5s often represent a change after the stability of the 4 so this 5 shows a change in your emotional state, maybe a loss of something so a loss of friendship would fit.. With the 5 of Cups there is also a feeling of focusing on the negatives rather than the positives (a lot of decks show 2 cups remaining upright, this one doesn't).. The lady certainly looks lonely..
5s are connected to The Hierophant too so there is often a lesson to be learned with them.. Something that is difficult at the time but that you'll look back on and be glad you lived through it because it helped you to grow in some way.
With the 8 of Cups there is a sense of dissatisfaction (again emotionally since it's a Cups card).. Since it's an 8 it tends to show that emotionally, you've put all you can into something and it's time to stop investing in that relationship or thing and move on to find what's missing (the 9th cup) somewhere else.
From what you've said, I'd go with the 5 of Cups..
