Feeling like a failure

I graduated high school in 2016, I never went to college because just the thought of it had my anxiety through the roof. I am now 20 trying to figure out what to do with my life. I know I want to do an LPN course (licensed practical nurse), it usually takes about a year to complete, I searched around my area and I found one for 20k so rn Im currently working as a cashier to save up at least half cause I know my mom will help me out. But I just can’t help but feel like a failure because my mom is always pushing me to do something, trying to get me in college, she says she doesn’t want me just not doing anything. It’s not like I lay around the house doing nothing, I have two jobs and an trying my best to save up, but when my mom bring up all the career talk, I just feel overwhelmed and like a disappointment 😪
