hello again! =D

I had a similar experience where I had achieved the goal I had been striving towards for so long and after I didn't feel the way that I thought I would feel. Fulfilled. I was sad/depressed for a while because I kept on thinking: "Is this it? Is this all there is to life?" On top of that, you're also stressing over your friend problem which is making this situation feel even worse.

I think you should try really hard to give yourself more time to relax and find a new goal to strive towards. =] Good luck!!
