I just graduated and I'm panicking about my career and education decisions

I'm 23, recently graduated with degree in psychology, and I'm panicking. I can't help but feel like a total loser because I didn't get a job lined up right out of school. I look at all the people with "cool" jobs and all the people who seem to have it together. I feel like I've wasted my life. This is my story.<br><br>I have a two younger siblings and both of them were diagnosed with disabilities. My sister is autistic and my brother is severely physically disabled. I'm not sure what cause me to feel this way, but I always felt like a burden on my parents and like anything I did was wrong. I had to help with a lot of the housework and I felt like I couldn't do anything right. I felt like if I expressed just one emotion or personal want I would be called selfish. I also became the live-in caregiver for my brother after I graduated. He is completely dependent on people for his basic needs. I never got to do the normal things kids did in middle school or high school, like sleepovers, dates, or parties. I could never just hang out at the mall even after I got my license. I don't even look like myself anymore because I started cutting off all my hair when my brother was born. It's not that I resented my siblings, I just resented the life I was given.<br><br>So now I'm working part-time as a direct support professional, helping people with disabilities and elderly people. It's not the best, but it's better than nothing. The pay is very bad, but it's also rewarding. I feel like I'm doing something good with my life. Although, it's also very draining. I feel like I'm stuck in my life and career right now. I'm afraid to ask for help or talk to people because I don't want to be called selfish or a burden. I feel like I'm just floating right now and I don't know what to do or feel. I'm not sure what I can do to get a better job or improve my situation. I also feel like I'm not good at anything. I feel like even if I tried to switch careers, I would be terrible at it. I don't know what to do or who to ask.<br><br>Also, I'm very financially unstable and I can barely pay rent, let alone student loans.<br><br>Any advice on how I can improve my career or situation would be appreciated.
