How to forget that someone was bothered by you talking to them?

So I have always been very sceptic about not disturbing people. I am very introverted and rarely ask for help because I am afraid people may feel bothered. Whenever some friend has given the hint that they prefer other people over me, I have left their company.

However, a girl from my class, as I came to know prepared a list of names knowing about which is very important. She told a mutual friend that according to that list, I have some issues and I may have a serious consequence ( I may not be allowed to sit for my semester final). So after much hesitation I politely asked her about it over text. She has always been on my contact list and she talks to me in real life. She gave some cold replies. Later, she told the mutual friend that she felt disturbed, bothered and creeped out. She also added that she had to waste a lot of time over me (barely 5 minutes).

Introverts will understand this situation I think. I felt extremely embarrassed and asked for apology from her. She said "it's okay, I don't mind". After that I blocked her from everywhere but can't forget it.

I'll surely feel uncomfortable to text any friend after this. How to forget this?
