Been years since I was in a relationship, but heck I still get that feeling regardless sometimes when I am in a downward spiral. Not to TMI ya'll to death but the self-love is a big deal for me, major source of stress-relief and sometimes the only good part of a whole day. But there are times when I am just so tired mentally and physically, too distracted or just too sad physiologically, so I just give up or don't bother trying.
