Even more confused than ever

I came back from a vacation, and everything has changed. There were long periods of time during the vacation where the bf avoided talking to me. The two of us buried our heads in our smart phones. I think my bf is getting sick and tired of me.

When I came back to work, the grad students found friends and alliances, and I feel like an island in my lab. New people have joined our lab, but I feel distant to everybody. Boss had a talk with me and while on the surface he acted like he wanted to help me, but really he's saying he pities me because he doesn't think so highly of me.

It was so good to see my friends back home though. The city was so green, so gorgeous. I felt like I could go back there today. Unfortunately neither job opportunities nor boyfriend potentials are abundant there.

The indecisive me has been activated. I am comfortable here, but the relationship is going cold. I want to find a good lab, but don't know if I am talented enough to make it into one. Does it make sense to take up some permanent job or to make another crazy move in some other exotic country or continent in hopes of finding a fantastic boss? Should I go home? Should I focus on my career or should I focus on finding true love?

Yoga / bodywork addiction - good or bad?

I don't have a disciplined 6-day Ashtanga practice.  Last year I established a semi-regular routine where I practiced some sort of yoga (Power or Hot) about 3-4 times per week. In December, I went on vacation in Asia for 3 weeks.  I had not been on a plane ever since I took up yoga, so I thought that regular yoga practice would help me settle easier on the plane since I had become more flexible over the last year. I was completely wrong. On the plane trip back to Asia, I kept feeling this great desire to stretch. I couldn't stop squirming around in my seat, doing hamstring stretches, neck stretches, spinal twists, arm stretches, you name it. I left my seat about 3 times to the back of the plane where there was a bigger floor space and did every pose that didn't look too ridiculous, including forward folds, mini dancer's pose, mild triangle, more twists, neck circles, etc.  I felt like I had earthworms inside of me struggling to wiggle their way out.  After 3 weeks of doing almost zero yoga, my plane trip back to North America felt much more at ease. I didn't feel the need to wring out all my body parts like a towel and stretch them in every direction possible.

I didn't go back to yoga class right away and recently I'm just slowly building up my yoga practice to 2-3 times a week.  Now I feel and probably act like a squirmy earthworm again whenever I'm sitting still. Doing mild stretches just makes me want to stretch more. I blame it on the excellent Thai massages and deep tissue massages and Ashtanga adjustments I've been receiving the past year. I feel like my body is suffering from pamper withdrawal.  It's demanding more frequent deeper stretches, more yoga poses, and quality massages. It's as if I have a drug addiction. I'm worried if I keep on doing yoga, am I just going to become more and more flexible, and is my body going to scream at me if I don't wrap my leg behind my head at least once a day?  I thought committing to a more frequent yoga practice was the establishment of self-discipline, which would be a positive thing; but this feeling of yoga / bodywork withdrawal is kind of concerning.

For those who have practice yoga regularly for a few years (or decades), do you experience the same thing if you take a break from yoga for an extended period of time (say, a few weeks)? I look forward to hearing your opinions/experiences.
