You could really have been describing my daughter. Tantrums don't only come at two. They can arrive early as you and I have found out. If I even suggest that my daughter turn around to walk the other way, full on hysterical fit throwing. I think she could actually win an award for how good she is at throwing fits. I can't even hold her. I'm not strong enough so I usually don't venture off alone with her too often. I too am left wondering if this will only get worse with age.
Take a deep breath and know that you are not doing anything wrong. Also, rest in the fact that it does get a little better. My daughter is understanding more and able to express herself more.
When my daughter was about 17 months, she started her major fit throwing. My neighbor suggested to get down to her level, ask her calmly to use her words. I did that and took it a step further and would suggest things to her that I thought she may be frustrated about. "Do you want up?" "Do you want that fork back?" "Do you want a drink?" If I hit the bullseye, she would mimick me saying what I last said and then she would stop screaming or if I triggered her interest for something, we would redirect her attention to that instead of the fit throwing. I now am always asking her to "Tell Mama" or I offer her my hand and tell her to "take mama...show me".
I think most of the fits my daughter throws are from her being so overly frustrated with not being able to express what she wants. And when we say no...well that is like the end of the world. She doesn't understand it is for her own good.
Hope this helps.
