Why is life not working out for me even though I’m working so hard?

I’m working so hard, and I’m just not able to get anything I want. I worked so hard this semester and my prof would just not acknowledge me. My group mate who barely did anything took so much credit. That’s fine like whatever. But I’ve put so much effort and I get bad grades. Lesser than my friends. Why am I not smart? Even when grades were fine I couldn’t apply for semester abroad cause my dad couldn’t pay for it. I’m not healthy. My habits are shit. I’ve put on so much weight. My life is shit. All my friends are travelling and seeing the world. I’m not even able to do that. I’m not able to work on any skills that I want to develop.

I just feel so shit. Everyone’s getting so many opportunities in life. And im not getting anything. I’m not even getting anything recognition. It’s like the world doesn’t give two shits about me. I’ve tried damn hard to stay positive the last few months. And I succeeded too. But just feeling down right now.
