When I'm feeling down and exhausted, I have to ask myself what I need. Do I need love from myself or comfort from my friends? Do I need to take some alone time and be by myself?
I don't know if you get to those places where you're just not feeling it and all you want to do is stay home and veg out. But I've noticed that there are times that I have to push myself to hang out after a long day, just because I'd rather be in my comfy pants (literally and figuratively). I guess I'd call that tough-love with myself.
Yes, we can be judgmental. It serves a purpose. Sometimes it tells us that we're feeling insecure about something and that's why our criticism of others or ourselves comes up. At the same time, self-judgment and judging others can be taxing. When we're critical of ourselves, we're actually making it harder to give ourselves that self-love. That criticism adds to our negative thoughts about ourselves.
For an exercise, you could start with acknowledging that the judgmental thought is coming about, "Hey, that's pretty judgmental. It's okay to judge. You're human. What do I need right now?" The reason that "it's okay to judge" is included is that it's about being kind to ourselves when we're being judgmental of ourselves and others. The next step is action-oriented. By asking ourselves what we need, we're creating space for us to take care of ourselves. So as an example, if we're tired and at work, maybe we need to take some long deep breaths for two minutes. Or maybe that means that we need to step outside and call a friend.
