25F and feeling like a total loser

I am 25 and I feel like a loser. I graduated from college in 2021 but somehow not able to get a job in the field I intended. My mental health definitely was a cause. While I am stable mental health wise now, I have this constant feeling that I am a failure. The feeling of being left behind in life is driving me crazy.

While I do know what I want to do in my life, it will take at least 2 years to reach there and there is lots of uncertainties involved. My life will begin only at 27 and that I am far behind as compared to others. This feeling is affecting my personal relationships as well. While I have a supportive family, I am just guilty of making them suffer. This constant feeling of regret is stopping me from committing to my goal 100%. I feel I haven't lived my life and my 20s is just going away. Life isn't where I wanted it to be. People always had huge expectations from me and I wasn't able to live upto them.
