<human>: Can you provide a brief rundown of the text in within 3 sentences?

I am a 20 year old male living with my parents. I have gone through 2 years of university, making some decisions along the way. Now, after having gone through a job as a Personal Trainer and deciding I didn't like it, I have no real idea what to do. I thought I wanted to be a P-Trainer for a good portion of my life, but now that that prospect turned out to be a dead end for me, I'm not sure how to proceed. I've been stressed and depressed for the past 3 weeks, jumping from job to job trying to find my niche in the world. I've also been fighting with my parents lately, with them being mad at me for not sticking with one job, as well as being so worried about my future all the time. They have said they will support me no matter what my decisions, but all they seem to do is criticize and condemn my decisions. I have some money in the bank, but my parents always find reasons for me not to leave the jobs I have. I tell them I don't want to do something that makes me unhappy, but I just get the lecture about how you need to do what you have to do what you want to. Problem is, I have no idea what I want to do. Biological Conservation has always been an interest in the back of my mind, and I want to pursue that in some way. I also really want to go back to university, but don't want to if I can't justify it. Outside of trying to find work, I enjoy reading, playing guitar, playing video games, and doing parkour. Not sure where else to turn for advice, so I'm hoping I'll get some ideas from the reddit community. Thanks in advance for any help.
<bot>: Depressed and confused adult with no idea what to do with his life after learning the career he wanted is exactly what he didn't want. Interest are guitar, reading, parkour and video games. Advice would be much appreciated.
