mid-life crisis?

was flipping thru my old stuff yesterday and had the chance to flip thru my photo albums, birthday cards, greeting cards, old letters - yup, those days we wrote letters when there was no internet, etc. was reminded of my sec school, college life, uni, NSF, etc etc etc and all the friends i had. was also reminded of my teenage crushes and closest of friends. suddenly, i felt a great sense of crisis, of panic, of depression. I felt that I had really not achieved much, at least for myself. Perhaps I had done lots for my company but for myself - none.

Then it also struck me that I had passed my prime, and I couldn't help but feel a total sense of lost and helplessness. It seemed like my life has fast forwarded and that there is absolutely nothing I could do about it, that I had not spent it well enough, that my youth, my life, my friends, my family, everything has not been lived up to what I had wanted it to be. Momentarily, I also blamed the people tat my life has revolved around (esp currently) for not giving me the fulfilment I had sought, my emotional, psychological, physical needs etc.

The more I thought about it, the angrier I felt, and after this anger, I began to feel depress. Lost. Helpless. Is this the mid-life crisis that everyone is talking about? or is it just me and my expectations?
