LIfe & Style magazine says that Samantha Ronson’s stressful life with Lindsay Lohan is making her sick. Sam’s exhaustion and depression got so bad this weekend that many panic-y late night phone calls to friends ended up with doctors at Sam and Lindsay’s pad.

In addition to the stress, depression and exhaustion, Sam’s “skinny pact” with Linday is taking a tole on her health as well.

“She’s been suffering from depression and from lack of food and sleep,” Sources say that Lindsay has “vowed” to stay by her sweet hearts side. As long as she doesn’t start eating and sleeping and get all fat and everything.
