It's okay to cry, especially in these situations. Cry as much as you need and if you ever feel suicidal or just need someone to talk to then find a hotline. There are many communities/platforms that contain people that have been through the same situation.
Remanence, remember all the good things/times you had! Know that as soon as they are out then you'll get to make more memories and have more fun times. You can listen to their favorite song, make up a welcome back song, look at pictures, visit places you went, ETC.
