Saw Sara this morning to talk about what the situation is on campus.  The meeting lasted lasted all of 10 minutes; she could see in my eyes that I have issues deep enough that severely limit who I am willing to work with, and that the people I would feel comfortable working with are inaccessible.  I didn't even have to say that my comfort level is with females only (she could tell right away).  We both saw there was no point in discussing it further -- in effect all of my on-campus options have been used up or otherwise proven unworkable because of my issues -- and so we left it at that.  Sara's an academic counselor, not a psychology-oriented counselor.  Makes a big difference.
I hate putting pressure on ScaredandScarred but that's basically what this does.  She's all I have left.  The recommendation was for me to bail out now, but I can tell you I just don't feel I can do that and expect to be able to still have my part-time job next semester, which matters because I still feel that both of my path options have to be protected at any cost.
The only reason why I haven't gotten a warning grade is only reinforcing the people issues: The prof is apparently putting so little stock in the labs that he only wants at a maximum three lab reports.  I thought I'd potentially be out 100 points on that; now it looks like the max loss is only 30.  But I don't feel good about that because for once my heart and my head agree: This gives me little if any incentive to break down my walls, so on the whole the odds favor the current pattern only perpetuating itself.
