Overcoming jealousy of partner's education/job?

[doubtful]

I've recently met someone and they are absolutely amazing. I love talking to them, and while our situation is unique and we can't actually meet for a couple of more months we've started a great relationship by phone. However, when I'm not talking to them I feel this incredible jealousy over their education and job. They've earned their Ph.D. and have taken a great job while I am still struggling to find out exactly what I want in life - but now all I can focus on is achieving the kind of success they have.

I thought I had things figured out and was pretty secure in the direction I was going. This is the second time I've had a partner that was more successful than me and I get this overwhelming jealousy which poisons the relationship.

The jealousy sends me into a deep depression that makes me feel so desperate and empty. I hate this feeling and can't stand having these thoughts any longer. Any suggestions on how I can handle this would be greatly appreciated before I ruin anything!
