> I grew up in a high pressure environment, where a lot is expected from you.

Talk to a therapist. You should find out which experiences from the past trigger your “laziness”. The past high pressure situations trigger a pattern in you. Discover the pattern, you’ll be able to understand why certain tasks cause the anxiety. Once you know where it comes from and why it happens, you can overcome that. Sometimes just a simple talk with a therapist can help, no need for pills.
