See, this question has a lot of sides. Even if there was a site where a student could write something about their supervisors it would not always be fair. There are different situations and different people. For example, when a student asks the supervisor "rate my thesis" (https://www.writemythesis.net/how-to-rate-and-grade-my-thesis-some-tips/) he or she can tell about all the gaps and inconsistencies, etc. But another tutor, who don't care can tell that everything is OK. And then a student would think that a supervisor is just a very picky man. So the best you can do is to think thoroughly about each factor before choosing a PhD.

The question doesn't seem to be a random one. I suppose a lot of people now try to deal with money saving. But there are a lot of pieces of advice on the Internet. Nevertheless, I will tell you some of them which I remember. The best you can do is to try to note each thing on which you spend your money. Do it during two weeks. It will help you to observe your spendings and to decide which are important ones. Also, try to eat at home, not to spend for an everyday coffee - a lot of people spend a lot on that.

Copying a lot of articles is a definite bad idea. People will consider this as a plagiarism. You can use some quotes only or some pieces of information (and of course, with telling from where is the information). You have to meet all your thesis requirements first of all. Capacity, style, format, etc. Then think about how valuable is your thesis. Is there something new and interesting? Don't make your work just full of dry facts, add interesting relevant information and analyze each aspect of the topic. It means you should not write only about the country in your thesis.

Speaking of presentation skills, we can highlight a lot of skills, which can make your presentation successful and unforgettable. First of all, take care about the content of your presentation: check everything from a format to a data given (statistics, years, names and so on and so forth). Choose the main idea which will prove at the end and which will be analyzed during the presentation. The better will be your preparation - the more confident you will be. Being confident during the seminar is also one of the factors which have a great influence. And also, practise your speech several times.

Hmmm, your question is a little bit complicated, a lot of students face some problems. But if I were you, I would try to find some companies in my area, which would be relevant to your experience and field. Then I would find some contacts or go there personally to ask if there is such a possibility to work/to volunteer. Send as many emails as you can, and, sure, you will find a company or an organization which will help. This is not the best variant and it is quite a time-consuming one, but you can try to do that.

You are so strong! There are so much of things that you have experienced. And I'm so sorry about the state of your health. What about your question, If I were you, I would take a minute to sit and to decide everything about my priorities. What is the most important for me? Career? Or a healthy and a successful pregnancy, family? And if the second, it doesn't mean that you have to forget about your skills and smartness, you just have to find another way. Try to find something else and don't stop. Even small grants, even small projects etc. Have a good luck!
