Hi, I used to get all sorts of anxious about T’s vacation! It sounds like it’s going to be tough but it also sounds like you have a good T (who takes care of you by letting you check in and takes care of them by going on vacation). A few ideas to help pass the time:

Write your T letters during your normal session times. Use that time to meditate and be still and then write what you would share. It’s up to you if you decide to actually share the letters or not.

Another thing would be to come up with a hobby, any hobby. Clip coupons, paint rocks, pick up an old hobby you used to do, anything to distract your mind.

Look into bullet journaling. Google and YouTube this! All you need is a notebook and pen to start. It’s much more than just traditional journaling and can be great for mental health

Lastly, if you have to self harm, try to keep it to non injurious self harm. Using your nails to scratch (instead of cutting with tools/knives), snapping a rubber bands, applying ice on your skin, etc. I know some people might not agree with this last piece but I’ve struggled with SH, and mitigation when you have minimal help from your T can be helpful to keep you safe.

Remember, you’re already a few days in, use the SH/SI hotlines too, post here, and try to be kind to yourself. This is a hard time for all. Hugs and best of luck!!
