Often people feel uncomfortable when they have to ask others for something. At the time of the request, a person feels vulnerability and dependence. However, it is worth changing the outlook on the nature of the request, and the sensations also change.
What prevents asking
Fear of asking may be the result of shame that you could not do something on your own. If you are an idealist or a perfectionist, it can be difficult to admit to yourself (and others) that you need help to cope with the task.
If you are scared to ask, then you are probably very much counting on a positive answer. At the same time, it seems to you that a denial of your request will be tantamount to death.
Another obstacle to asking another person is the reluctance to become dependent on him.
