However, it doesn't exactly mean any of those things. The two words are not necessary for the sentence as "I taught myself" would be fine. We add those two words in a lot of places without an exact meaning.
See if these make sense:
I can't decide whether to got out tonight or not. I'm sort of tired but awake, if you know what I mean.
I don't know how I picked up that car. I saw my child trapped underneath and I just sort of did it.
I can't really describe that colour to you. It's sort of brown with a hint of caramel.
I love your shoes. They're sort of elegant without being posh.
I need to take my car to the garage. It's making this sort of grinding, crunching noise. There's definitely something wrong with it.
Also, please note the amendments I made to your post:
- There is no need to post in bold.
- Start every sentence with a capital letter.
- End every sentence with the appropriate punctuation mark.
- No space is required before a full stop, a comma, a question mark or an exclamation mark.
- Please don't use textspeak, like "tkx" - use "thanks". Other learners read all these threads so we use the full correct English spelling of words to ensure other people don't think that the textspeak versions are acceptable.
