If loving yourself means, "caring about oneself, taking responsibility for oneself, respecting oneself, and knowing oneself", then I guess so. If I didn't do this, I would make it hard on the people who actually care for me. The last thing I want to be is a burden or a metaphorical bum. I don't need people attempting to "rescue" me.
If it involves anything more than the aforementioned definition, then no. For I'm just a spec within a spec within a spec within another spec within a universe that is supposedly spatially unbounded and ever expanding. Not to mention the speculation that this could be one of a finite but ever increasing number of universes. Insignificant doesn't even begin to describe it. I'll just make sure that I help everyone as much as I can while staying out of their way as much as possible. True, that impact still insignificant in the grand scheme of things, but what would be the point of existence otherwise?
Basically, I don't think I love myself.
