Administrative stuff

The loss of a student

We’ll start with a minute of silence.

• There is drop-in support space at the CRSSJ from 9am to noon.
• There is drop-in support space at JRC 202 from noon to 3pm.
• The weekly Grief Group meets Mondays from 4:15–5:15 pm.

Some thoughts.

• I don’t have special expertise in loss, other than having experienced it multiple times. Nonetheless, I’d like to share some thoughts with you.
• It is human nature to want to know more about what happened. However, we don’t have the right to know more. Asking can place a burden on those grieving or add to their grief.
• It’s okay to feel sad, even if you didn’t know him well. The loss of someone your own age can feel particularly painful. It may also bring up other losses in your life.
• It’s also okay not to feel sad, even if everyone around you seems to be sad. We all react in our own way and in our own time.
• Please try to find the time to take care of yourselves. I know that’s especially hard amidst the end-of-semester work. But try. I hope a quieter week in 151 will help.
• Please pay attention to those around you and offer the support you can. A hug. A note that you’re thinking of them. Time to listen. All of these can help.
• Please ask for help when you need it. You are all high achievers, and you may not be used to asking for help. But it may be necessary right now. You may also not know what help you need. Sometimes saying “I need help” can be enough; others can work with you on figuring out what’s right.
• This may be a particularly important week to visit the therapy dogs.

Sharing

• I debated whether or not to set aside time for sharing, particularly since there aren’t trained professionals in the room. But we can still support each other, so I’ve set aside a few minutes in case anyone wants to share.
• If you’d rather not be here for that, pleases step into the hallway. We’ll bring you back in when sharing is over.
• Reinforcement: Things will come in waves. You can’t be prepred, but ask for help!

Introductory notes

• SoLA 3 has been moved to next week.
• MP 9 will be in week 13.
• SoLA 4 will be in week 14.
• I think we’ll have a visitor on Friday.
• I’m running out of Otter.ai time, so I’ll only be recording section 1.
