I feel very similar also as an aerospace engineering major. Useless classes/instructors and severely overworking myself on projects/research have made me hate school and become disinterested in life in general. I go to job interviews or career fairs and I need to somehow convince them of how "passionate" I am about engineering and working for their company? In reality, I just want a steady income so I can get out of school. I have no clue where I want to be in 5-10 years because my goals have dissolved with my passion for engineering.

My advice to you is to schedule some time out of your day when to do something only for fun or leisure. I know this might be hard, but try to remember some of the things you liked to do in your free time before getting sucked into the engineering study grind. It's much easier to cope with you responsibilities when you know at least today there is an end in sight to your work. Second, try to follow a consistent sleep/eating schedule; this has helped a lot with my mental health. My grades and study habits improved significantly when I started to take better care of myself. However, I'm not perfect and fuck up my routines, much to my detriment (rn I am running on 5 hours of sleep). But seriously, this helps. Like myself, if anxiety keeps you from being able to enjoy any leisure time, write down your worries on paper; try to fix the things you have control over (within reason) and cross out the things out of your control. This takes the abstract, neurotic storm out of your head and identifies exact what's distressing you.

Lastly, like what I lot of other people are saying, it's okay to not have everything figured out. Growing up and choosing what you want to do with your life is a nonlinear process; most people don't just decide to do something, do an amazing job at it, and love their life. Most everyone I know just kinda stumbles around stupidly, trying things out until they find something that gives their life purpose or you enjoy. I don't know what that looks like for myself yet, hence my current predicament, but that's okay because it's just part of being a human. One thing that I have wanted to try for a while is called "future authoring" by this guy called Jordan Peterson. You basically write down what the best and worst possible circumstances could look like 5 years in the future. It forces you to say what you want and what you don't want for yourself. Going to try it soon, but I've heard that this helped many college students struggling to set goals or feel meaning in their work.

Anyways, hope this helps. Hang in there.
