you’re all right, and all of the above points should be taken into account. Kiruv can be good for the person doing it or it can be detrimental. Anyone who works in Kiruv has to continually do a cheshbon hanefesh to see if it is causing him to go down in any way. If he sees
that it is, he must find a way to counteract that or get out of kiruv (depending how badly it is affecting him and if he has a way to avoid it).
When I was in seminary, I attended a program on doing Kiruv. I remember that one of the speakers stressed the fact that you must make sure that you set aside time for your own spiritual growth.
If you do go into kiruv, Sparkly, I think you HAVE to make sure that you have a Rav/Rebbetzin/mentor whom you are in constant touch with for both aitzas and halacha sheilahs.
I do think that doing kiruv could potentially be very good for you, but you must have some guidance while doing it.
Hatzlacha!
