Again, as I outright stated the first time, it is not ignoring emotions.
Rather it is more like this:
Say you have claustrophobic reactions, stemming from some vaguely remembered event in your early childhood. You do not even properly remember the experience, you just know that now, later in your life, you have profound feelings of anxiety, helplessness, and fear when you are in a closely confining space.
Rather than go "No, I do not feel that way, I am fine! FIIIINNEE!!!" and stomp your little feet, (which is what actual ignoring of emotions is)-- you instead go "No, I am not fine. Why am I feeling this way? Is there something in this situation that warrants these feelings? Is there some way I can moderate these feelings, so that they are not an oppressive burden to me?"
EG, combating those feelings with pure reason.
This is because, as I cited, negative emotions are more strongly tagged and retained by your brain. This makes some evolutionary sense, as things that harmed you, or terrified the bejesus out of you in the past, are things you are going to want to avoid in the future, and having severe anxiety about those things will help you ensure you stay the hell away from those things. In the modern world however, this does not really serve us very well. We are no longer little tree monkeys, fearful of the big bitey things on the ground below.
For the hypothetical claustrophobia situation, if I were the sufferer, here is what I would do:
I would leave the door to the confining space open, then place things that are fun and enjoyable inside (then avail myself of the fun and enjoyable things). I would acknowledge that I have anxiety and apprehension about the confined space, while simultaneously rationalizing that the fear is unjustified-- I would combat the anxiety by having a clear and unobstructed means of egress, and reinforce positive experiences (with the fun and enjoyable things in the enclose space) inside enclosed spaces, to slowly re-modulate my emotional experiences with such environments.
I would likely never stop having a pang of anxiety in such a circumstance; It would just become tolerable and not oppressive.
Again the issue, is that this requires a person to override the intrinsic program that the emotional tagging in memory retention is theoretically there for-- To protect you from stressful, harmful, or painful circumstances or environments, by dissuading you from doing or going to those things or places. To do that, requires that the person strongly use strong reason to evaluate the emotional imperatives they experience, and then rationally determine if they are justified or not. Most people simply trust their emotions and emotional responses, without question. This is why anxiety and depression are so horrible for most people.
I have indeed grappled with depression. Several times. That is not unusual however;
the statistic is quite alarming. I have been able to honestly evaluate that I have experience depression, (and can evaluate when I am feeling depressed), then engage in conscious self-modulation to alter the cycle that normally transpires with depression. (That cycle being increased degrees of inward isolation, and increased premeditation on negativity and negative emotions and feelings.) The last time I suffered a bout of depression, I hopped in my car, and went to visit a friend for a week. We did all kinds of fun things, and had a great time. 10/10, highly recommend.
It is important to understand that this is not a magic bullet; the mechanisms at your disposal are slow and gradual, where the impact of a negative experience are visceral, rapid, and often quite pernicious. Do not expect to just well-wish your emotions away; that is not how this works. You will feel all that anxiety when you sit in that small cubby with your pizza rolls and your PS5. However, if you saturate the experience well enough with positive feedback, you will want to go back in there and do it again-- THAT is the cycle you want to foster, since that cycle will make you able to tolerate other, admittedly less fun, confined spaces later.
