Jan 2021 usage 3x that of any month in the past year

I live alone and in the past 6 months my data usage history has gradually increased. Since it only goes back 6 months there's no way of seeing back to last year possibly further back. I'm disabled and nothing in my household has changed in the past year. I do watch Netflix and other streaming apps but I find it hard to imagine I could possibly go over the data cap. I received an email stated I'd reached 75% after watching under 2 more hours on hulu I'm now at 90%. I listen to audiobooks majority of the time. I do use my wifi to download these audiobooks but on average my phone states I use 150gb of wifi data monthly. I read the Comcast statement very few customers ever exceed this limit. Theres 5 days left this calander month. Although I won't be charged yet I have absolutely no doubt I will exceed this limit. I even changed my habits when I found out about the new limit and I'd reached 50% one week ago. In the past I put on the TV to sleep to streaming a series. I stopped this and changed the settings on my roku to ask if I was still watching every 4 hours. I have HD capable tv's but not 4k. The only other thing I use is my phone for shopping and checking emails. If I went over can you imagine what the bill will be for a family of four or more playing games, virtual classroom, video streaming and working from home. I already pay $70 monthly with the new $5 charge for streaming services. I cannot and should not have to add an additional $30 monthly for unlimited. I also have my phone service through Xfinity so I'm unable to switch providers without paying a large penalty monthly to keep my phone service without their internet. Everyone is going to pay for those now forced to use more internet due to the covid pandemic.
