Quick(ish) backstory:
K and I have known each other since high school, almost 8 years now. For a great portion of my teens and 20s we were inseperable. K, along with our other friend A, and I are so close as to have decided to get matching tattoos. About 3 years ago, K started having some serious problems. I am not sure whether she had problems with depression in the past, she always seemed very happy and upbeat, and if she did have any problems outside of normal teen angst, she never mentioned it to me. Nowadays, however, she seems very depressed, withdrawn, and constantly struggling.
It started off with a few pretty horrific incidents. First there was getting raped by an acquaintance. Then, she invited a coworker she’d just met to a party, who brought her mentally unbalanced boyfriend along who got drunk, became violent, and stabbed 3 of the party-goers, including K (everyone’s fine and he’s in prison, thank Og). Shortly thereafter, K decided to move to NY to get away from her problems. She spent 2 miserable years there, became involved with an asshole boyfriend, made very few friends and worked close to 80 hours a week. She got paid shit (on salary, when you averaged it out she made about 5 bucks an hour) and spent most of her off-time smoking pot alone in her room. She eventually moved back home.
But, things are just as bad now that she’s moved back. She finally found an awesome guy who treated her well, but her own doubts and insecurities plagued her and eventually soured the relationship. They’re not together anymore, but still friends. She’s got her own (really awesome) apartment, a car, a good job, she’s started going back to school, and volunteering. Things on the surface seem to be looking up, but she rarely hangs out with her old friends, won’t answer or return phone calls (not even her mother’s), spends all her money on pot, and just doesn’t seem happy.
She won’t talk to me anymore, I only occasionally see her a social functions like her brother’s birthday. Our other friend, A, has given up trying to get in touch with her. A feels the same way that I do, that she’s stuck in a rut and depressed but won’t reach out to anyone.
I don’t know what to do. Part of me worries that K is in big trouble and needs help, the other part wonders if maybe we’re just drifting apart like friends sometimes do. Should I just write her off, let her contact me if she wants to, and say good riddance if she doesn’t? Should I make some effort to be there for her, even if she’s not receptive? I suffer from depression as well, so I know how it is to lock yourself in your apartment and ignore your phone, but even I eventually snap out of it. Help?
