Today was boiling! I thought I was going to faint.- The word 'boiling' is usually used when we talk about water getting to 100 degrees (water's boiling point) but we also use it when we talk about really hot temperatures. 'I am boiling!' means 'I am really hot.' It can be so hot (boiling) that you may faint. Fainting is when we 'pass out', 'collapse' or lose consciousness, due to heat or feeling sick. It was so hot today, I thought I was going to collapse.- this is a good way of describing what happened, in the past, as a result of something else happening. 'I thought I was going to collapse as a result of the hot weather'.

Today was so hot that I thought I might collapse/faint.- This means that it was very hot and you had a feeling that you may collapse/faint. Remember we say "so......that...." For example: "I was so tired that I ended up sleeping." I felt like fainting/collapsing due to the extreme hot weather today.- This means that you had a feeling of fainting/collapsing due to the hot weather.

When you feel like you are going to collapse as well as saying 'collapse' you can also say 'faint' or 'pass out' these all mean the same. So you could say 'It was so hot today, I thought I might collapse/faint/pass out' another way of saying this is 'I nearly fainted/collapsed/passed out due to the heat today' these are all good ways to explain what you mean

There are many ways we can say this: 1) "Today was so hot that I felt as if I was going to faint." - This tells the person that the heat was unbearable, and that it was affecting your health. 2) "It was so hot today that I thought I was going to faint from being overheated." - 'overheated' is a word we use when our bodies get too hot and make us feel unwell. 3) "I felt as if I was going to pass out from the heat today." - 'pass out' is a common way of saying 'collapse' or 'faint'. For example: "I passed out from being overheated."

The two sentences you see provided above are great ways to express to your listener that you thought you were going to collapse from the hot weather. In the first sentence you will see the term pass out. This means to faint. This term is appropriate for informal settings, like talking with close friends or family.
