No matter what you do you won't be able to make her happy in the state of mind she's in. You're only going to get pulled in all directions. She needs to be alone for a while and learn to sink or swim on her own because she's clinging to you for all her emotional problems that you aren't responsible for. It's not your job to make her happy, she has to be happy and bring something to the relationship instead of sucking everything out of it
