Hey maylyn and welcome to the forums.
In terms of advice, my advice to you is to remain flexible in your thinking.
Chances are you will not have a good idea specifically of what you want to get into, and this is a normal thing. Many engineering programs, at least my country have a flexible first year where you do foundational physics, chemistry and math and don't lock you into a specific stream.
On top of that, a particular degree or pathway does not mean you have to do a certain specific job. If you read other posts on this forum you will see what I mean.
Also it can be a good idea to get acquainted with things that are non-technical. It may not make sense now, but it often helps in unexpected ways.
So yes, don't be stressed about having to make this kind of decision now, and if your flexible and have a good attitude, then that will be a good basis for getting anywhere in any field.
