You really should talk to someone you trust ASAP
It’s very important somebody knows what you’re going through so they can help.
In the meantime you can always fill your time up with fun, positive things, I personally like animes and video games like Mario because they’re simple, fun, and distracting.
Also make sure you eat regularly and healtly, and get plenty of sleep. Those are just some tips to help with the brunt of the load.
