To the OP: I think bringing this up to your therapist may be a good idea, not because you have done anything wrong, but because it illustrates the difficulty you are having with the less frequent session schedule. Perhaps you could bring it up to your T without judging yourself negatively for it: "T, these long gaps between sessions are just not working well for me. In fact, the other day, I had such a need to feel a connection with you that I just sat out in the parking lot for the proximity." Just leave it at that. That is all you did and it doesn't seem like you had any ill intent or did anything that was in any way invasive of your T's privacy, and I don't really think it needs to be framed as "stalker" by you, and I suspect if approached that way, your T won't get that sense from it either. Maybe in framing it that way, you can really talk about the problems with connection and attachment without getting into judging yourself harshly for what you did to cope the other day. You may also find, in just being honest with your T without attaching any negative context to it, you may be able to find ways to cope without having to physically be nearby.
