Hi! I'll be glad to be of help with this issue.
I can imagine how distressing this situation must be for you. You have two parts to your question and I'll address both, whether lorazepam is a good idea and whether to bump the Paxil back up to 20 mg. Oh, and whether to continue with Lunesta as well.
You've had a tough life stressor that has increased your anxiety breaking up with your girlfriend. And this is actually the key to my answer to you that you need to consider and think about. I'm glad you're taking steps to try to work things out with her. This time in particular, then, is not a good time to get off your main medication that has been working well for you this long. If, then, you could delay tapering off the Paxil till this stressor is more resolved, that would be an advantage. And so going back up to 20 mg would seem prudent as that dosage was effective for a long period.
Lunesta is a sedative and that you would be sleepy all day and sleeping longer than you expect is something that many people experience with sedatives. If you can drop Lunesta from your medications list, that would be an advantage for you. You need to maintain your daily routine as much as possible when in a stressful period and if you are reacting strongly to the sedative properties of Lunesta, then avoiding it would be good.
Lorazepam (Ativan) is indeed highly habit forming. The medical community is much more wary of prescribing it as a daily long term medication today because of this recognition. If you are doing well with the Tylenol, it is to your benefit to not let your system get used to lorazepam as the withdrawal can be harder than with Paxil.
I think your intention to return to psychotherapy with your LCSW is an excellent one. It can be helpful and it can keep your medications list smaller. If you can't reconnect with your LCSW, don't hesitate to find someone new.
Okay, I wish you the very best!
