Hi Lynn
I'd recommend moving this post to the anxiety and/or depression room/s. You would have a better chance of getting helpful responses.
I have a very low self-esteem too. People have recommended that I make small, tangible goals for myself to achieve quickly (within weeks). Write the list of goals for myself, check mark besides those things that I've achieved (to remind myself that I have done things). List other more long-term goals, but only a couple at a time. A long list of long-term goals can feel overwhelming, so keep most of it relatively simple.
That's my advice. Best wishes to you!
