Hello! Long story short, I have a BA degree in education but at the end of it I wasn't sure if I would love to work in a school or not. I finished my degree in 2020 after online classes because of the covid, it was extremely difficult for me to have all my exams online (they were all oral and I had a lot to study in a short span of time). 

While I'm proud of my accomplishments, everyone in my family doesn't really appreciate it since my sister did something more of the future, that it will bring more money. (She has a BA degree in nutrition and now is in medical school in order to become a doctor) 

I took an year off since I was on the verge of going crazy last year after everything. My mother supported it since my sister did the same before applying to medschool. 

But this year she told me that I should try and do another degree, and I said ok. But since I do not have any specific dreams or something that I desire I applied for a Computer Science program at an Engineering college. 
I start next month but I'm terribly anxious and afraid... I'm afraid that I'll never be enough, that I can't live to my family's expectations. 

I'm also afraid of a new beginning, new colleagues, new environment since it's a new city. I wake up a few times every night while I think about everything that could happen.

I'm pretty sure I'll do well since I like to study and  I adapt to new thing well but sometimes I'm overwhelmed and I feel something on my throat, like a pressure. I experience this when I'm stressed. 

The question is, why am I so anxious and overwhelmed when I know I'll be fine? My first time in college was so nice, I was so happy and nothing to be stressed about. Did the covid affect everyone the same? After covid and all the quarantine and isolation I feel like another person...
