I work with ppl with suicidal ideation and past suicide attempts, if you think it is serious, please seek medical assistance, generally speaking having plans and carrying out the plans is considered decently serious. If that's not something you want to do there are other things you can try, usually physical activities can help a decent bit, or leaving the house to go to somewhere with lots of people and just let everything stimulate the sense can also help.
