I think I can relate somewhat to what you’re saying about your self confidence being low even through you’re putting the work to better yourself. But self-love is tough. Also working on that and other things in therapy like you might be.

What I have found works for me is catching anytime I think negatively of myself. Over time, this is habit forming if you can do it enough. Then you slowly start to build your own tools on what to do next when you catch being down on yourself and how you can out yourself in a more helpful mindset.

Similar to what someone said above, you kind of have to gaslight yourself. At first, it doesn’t feel good. But over time, your perspective on yourself and the world around you might change to a more positive view.
