The first one (from an American perspective) is obviously sexy, but those burn marks and bruises on her thighs lead me to believe she isn't in very healthy situation. It looks like cigarette lighter burns or cigar burns. The second probably has a similar situation but not as severe (still bad) and she uses the fake positivity of her friend to stay uplifted, but she's an emotional drag on her friend and she won't be able to support both of them for much longer (her own concerns are drowning her already).
Maybe I'm completely off-base, but I don't think I am. If you find I'm right (or potentially right, your view of right may be extremely skewed) PM me. I can help you get out of your situation, and we'll never exchange names or anything like that by the way. You both can either stay where you're at and continue to be miserable the rest of your lives or you can do something about it and change your circumstances.
