What is a thesis for why it's necessary to accept help to overcome a difficult situation?

A thesis can be defined in several ways, one being that it is the point of a paper; what you are trying to prove. It is also sometimes referred to as the argument or claim and is normally written in one or two concise sentences at the beginning of a paper.
A thesis statement connects the main idea of any given argument and in the context of a student’s written assignment, it is a statement that summarizes the main topic of the paper and also declares the student’s position on it. Moreover, it readily explains what the paper is about so that the audience can decide whether or not the paper or essay is worthy of them taking the time to read it, particularly in its entirety.
No matter what kind of paper a student writes, from an informative or personal essay, argumentative paper, or a compare and contrast analysis, a thesis is required. If a writer foregoes a thesis statement, their argument holds no weight and the information they are trying to convey to the reader is ill-defined.
Everyone encounters difficulties at different times and for a wide variety of reasons. For example, children learn how to use the bathroom, tie their shoes and tell time on a digital or analog clock. As adolescents, we memorize the multiplication table. Your question serves as an example of reaching out to someone [in this case, a tutor on an online platform] to gather information (new knowledge) on the subject of a “thesis.”
Contrary to what some people believe, asking for assistance is far from being a sign of weakness. It actually demonstrates you realize that you lack the knowledge to solve a problem and seek out help from someone you trust. Generally speaking, most people delight in helping another person.

There are a variety of ways to write a thesis, but for this particular topic, I recommend using what I call the "point and counterpoint" thesis format. The first point that the thesis states is actually the opposing argument that your counterpoint is going to try and disprove. The reason that this format is a good format is because it forces the paper to admit to other arguments. That way readers know and understand that the writer is aware of those things despite being against them. It makes for a much more balanced paper.  
I don't know exactly why you believe it is necessary to accept help in a difficult situation, but a thesis can still be produced that will guide the following paragraphs. Start with the word "although." It forces the first part of the sentence to be a dependent clause, which will then be followed up by the main argument in an independent clause format.  
For example:  "Although many people fiercely hold onto the idea that being independent is critical to success, in reality, problems and adversity are much better overcome when a person is willing to seek out and accept help."  
This thesis allows you to discuss what it is like to overcome a difficult situation without seeking help.  It then allows you to prove why accepting help is preferable to the previous situations.
