What are suicidal thoughts? 

Suicidal thoughts, also known as suicidal ideation, are an ample concept related to a person’s curiosity, contemplation, thoughts, and planning death and suicide. It can happen in many forms, it can come in a fleeting moment, or it is a persistent idea.

This phenomenon may cause a person to think that people might be better off without them, that they don’t want to be alive anymore or that they just want the suffering to stop.

Although it is hard for a family member or friend to identify with someone is having suicidal thoughts, some signs can indicate a person might be contemplating suicide, like expressing hopelessness about life and the future, intense mood swings, showing curiosity about death and dying, change in sleep patterns, increase isolation, letting go of their belongings and self-criticism.

There are some stages of suicidal thoughts, passive ones when all the person wants you to turn off from reality, so thinking they want to sleep forever or disappear. In that case, suicidal thought is a way to stop the suffering.

But in some cases, it can be thoughts about death and dying, when the person starts thinking how people would go on without them, how they would do it, and they might start planning it. That is a stage people should be careful about.

What are their causes?  

Suicidal thoughts can come because of many reasons, and studies still try to establish a common line that would englobe how all people start having them.

But one thing that seems to be common is that suicidal thought can be related to the wish of ending the suffering, it might come from a mental illness the person is going through, such as major depression, bipolar disorder, schizophrenia, borderline personality disorder, people with eating disorders and with post-traumatic stress.

It can also be related to some trauma a person might be experiencing, it could be the end of a relationship, financial or legal problems, the death of a close person, history of self-harm or previous suicide attempt, history of physical abuse. Along with that, people who abuse the use of alcohol can experience suicidal thoughts triggered by the abuse.

What can I do if I get sudden suicidal thoughts?  

The first thing is to try to understand your feelings. Are you thinking about death in a curious, but not the active way? If that’s the case, you might want to share that thought with someone, and if you are in treatment, share it with the professional that is working with you.

Talking it out will help you understand why you are feeling what you are feeling. If any triggers caused these thoughts, how you can deal with them as they happen in the future. This can also give you a sense of control of your feelings, which can be a good thing since you might realize you won’t succumb to your thoughts.

If you don’t feel like talking it out, just reach out to friends or family members, Be with people you love and that love and support you. Depression and other mental illnesses that are related to suicidal thoughts tend to make people self-isolate, try to open themselves up to be with people.

It might not seem like it will help, but feeling the love and support of others might make those suicidal thoughts feel less urgent and desperate. It might be good to distract yourself from that, at least if for a little while

Another thing that might help is looking for other distractions, finding something else to focus on, like a tv show will help while you wait for the thoughts to go away. Some people might consider suicide because they think others would be better without them.

When that happens to you, it could be a good thing to question those thoughts. Try to think that your family and friends would be better without you if you can think that over, you might realize that is not really like that.

If that is not the case, and you are in a crisis and experiencing suicidal thoughts more actively, meaning you start thinking about how to do it, and plan the events, the first thing you might want to do is get in touch with someone you know and trust.

At that time, you can get in touch with a therapist, a friend, a family member, or even contact one of those suicidal helplines. The goal here is to be in touch with someone that will help you calm yourself. 

When we are dealing with a crisis, it won’t be the moment to understand what happened or what triggered it, when you get out of the crisis, you can talk about it with your therapist and understand better what happened. But at this moment you need to be with someone that will give you support and orientation on what to do.
