This has been me the past week or so:

I give significantly fewer ###$ about pretty much everything. It's been great in some regards. I have significantly less social anxiety and have stopped being so obsessed about how others view me. I also just feel so much happier without all of the excessive worrying. It's freeing to care so little when I'm used to caring so much about everything, especially other people. It has been negative in some ways, like with motivation in school, but I'm finding that my vyvanse that I just started has helped significantly.
However, this is supposed to be a negative side effect not the point of medication. As much as I'm enjoying it, I'm wondering how healthy this is and if I should go off of it. I'm afraid of going the other way in terms of other people. Right now I have zero interest in finding a partner or dating at all. I had sex with someone I met and there was no cuddling or discussion of meeting up later and I felt just fine. I feel detached and uninterested in other people. It's lovely when compared to feeling a need to be with someone and being so easily attached to others.
Is this just me being normal and not so clingy or is this a negative side effect?
