you can not be emotionless that would be you dying and coming back as a zombie. Upthe reason why would one ask this question, you are emotionally not in control of yourself, as a result of which some of the emotions end up making you capative to certain situation, people and relationships and it happens a lot, most of the time people stuck in a loop because of certain emotions, it could be the job, and same relationship, the same friendships, same pain and all those things are not benefiting you any way you would call progress.
step 1: you need to evaluate and break down what is it that you do or are doing that gets you introuble for which you blame certain emotions in you so sit down and really see before your eyes "what happens", "where you make the mistake", "how the person take advantage of you if person involve" you need to walk through the moments in your mind, "i was fine untill this moment" whatever they said becomes the trigger to your vulnerability and making you lose control that's the point you need to find. you'd be able to see where you are messing up and what things trigger you for messing with someone.
srep 2: Acknowledge whatever you find out real as real concerns, these are not to be ignored, hold it handle whenever you get the time or to be dealt with later.
No, whoever you are. these things are affecting you on daily basis, weekly basis, they are real and live with you. these are to be taken care of.
if somebody knows you and uses to disturb your mental staibility anything, take care of it right now.
step 3: Recognize in short sentences your weakness and emotions etc..
let's say you trust people too easily, and then they turn out to be anybody, which usually end up hurting you so "what does that mean"? you are a poor a judge of character. say this to yourself everytime you meet with a new person.
say stop this, i am not going to judge anybody, not going to say this is a great person on my firist impression of this guy, girl, man, superhuman, dont give a shit. I will reserve my judgement untill i have enough data because at that moment you don't know him/her as a person.
Basically, people think I wanna be like them, clearly they are awesome, they are not, there is chance you end up hurting poeple because you have approval and they seem normal, you go off chasing new people to want to be liked them so forget all these things, go to therapy and work on yourself. settle with giving yourself approval by setting your goals and achieving them so condense your excessive emotional strands are into needy, bad judge of character, too caring with these three steps, you can atleast make yourself aware of your weaknesses and vunerabilities.
these are also the things that will contribute to self harm, reduced self esteem, and bad moods spoiling your entire day so stay away from this kind of emotions and figure out, try to control.
