I recently joined a new swim team and was thrown in with people who were twice as fast as me. I’m a fairly new swimmer and I started off having to keep up, hence, I never warmed up, got so exhaused after I felt like I needed to pass out. It was the most horrid experience ever!
Is there anything dangerous about not giving yourself an adequate warm-up and pushing yourself to anaerobic levels so soon for so long when you’re not use to it?
Would it be more wise for me to get private coaching rather than swim with a team without direction and just effort.
Again, I’m new to triathlons and am only starting with the sprint and olympic size one’s but would sure appreciate some help.

You know you don’t have to keep up with the fishes. Push yourself while you’re there certainly, but trying to swim way beyond your ability has some obvious pitfalls. That said, if you survive and thrive in the long term, then you will be golden. Unfortunately there’s no way to know ahead of time whether you will sink or swim…
Another option is to swim solo/coached most of the time, then jump in with the Masters once in a while and bust your balls. That ought to keep things fresh.
You just need to find your stroke - you have to learn the technique 
Stay with the team, but find yourself a different lane. That way, you can swim at your own speed, but also have the benefit of good swimmers, and hopefully a coach, around to help you. Watch the good swimmers and how they shape their strokes, and ask them to watch your stroke and find the flaws (for instance, a lot of beginning swimmers ‘cross over’ their arms - that means reaching over the midline of your body when your arm is entering the water). You can do the same workouts, though you’ll probably have to adjust your intervals (if the fast lane does their 5 x 100 set on 1:15 you might do it on 1:30).
Search for “The Swimming Drill Thread” - fishtwitch has thrown a lot of good stuff in there
swim drills help work on specific parts of your stroke. For example, Fingertip Drag forces you to recover with a high elbow. You really just need to get a feel for the water, and how to breathe. But once you get it, it is the best thing in the world. You dive in and just melt.
Keep at it, swimming rocks.

c) focus on keeping your torso as straight as possible, keep the twisting and turning to a minimum
but your hips kind of rotate in freestyle (backstroke too)
