<human>: Give me the gist of the text in a nutshell

Last week my girlfriend[F,24] came clean about spending a bit longer at uni then usual. She has been going to counseling and her counselor told her she needed to open up to somebody close to her. She has always had forms of depression starting from age 17 when she was told she was losing her eyesight, then a big downward turn when her first corneal operation caused her to lose 95% of her sight in one eye. We have gotten through it all quite well she has had counseling in the past so it's no worry to me that she is going again. What did surprise me is coming home from work and finding her crying in front of two boxes of paracetamol.

2 Days later My best friend [F, 23] rang me to tell me she had been diagnosed with severe depression and was told to open up to somebody close. She has always been carefree and the idea of her suffering with depression has hit me harder then I thought it would.

The night afterwards while visiting my mother [F, 51] she dropped the bombshell that she had been prescribed pills for her depression. We are sitting down tonight to talk more about it.

I'm lost these people are the people i go to when I have problems but now I feel like I have nobody. How can I rant about my petty shit like Jane from work nicking my Pork and apple sandwich from the fridge again when these people have actual problems and i need to be there for them. 

My girlfriend said I've felt distant for the past few days and I can feel it personally i'm just a bit lost and feeling like i'm watching myself in the third person. I need to find a way to kick myself out of this rut and be there for the people who matter to me.

Getting to the end of this feels more like a rant then a question. So i'm guessing a number of people here have had experiences with close family and friends with depression how do you be there for somebody in that way but make time for yourself ?
<bot>: 3 of the closest people to me have severe depression and I need to be there for them but also find a way to be there for myself
