You just described me exactly 2 or 3 years ago. I had extremely low self esteem. Have you tried talking to your boyfriend about this? Because for me talking to ppl you’re close to seems to help the most. Also try to eat healthy, exercise and get enough sleep. And ironically getting outside of your comfort zone helps. I could keep listing stuff, but google is free y’know. And ofc if all else fails - therapy.
