last resort

Im at my wits end. Im seeking the words of strangers in effort to find out what the hell I want to do with myself. with my life. How pathetic is that? Im 30 years old. I'm quite intelligent. have 2 different degrees and I dont want a career using either of them. Im thinking about going back to school for a 3rd degree that I probably wont use but I feel like I'm wasting my life. I have so much energy and hopes. Ive researched so many different aspects and niches to get involved in...nothing interests me!!! HOW CAN THIS BE!!!! we all have a purpose. why am I having such a hard time. Im desperate and would love to hear anyones insight. Ive tried everything...Ive tried being patient and having faith...but the only thing that has changed is my age!
