Help me out If you went through same !

Hi everyone, I’m a 26-year-old male living in Pune as an engineer. I moved to Pune two years ago with my girlfriend, with whom I had been in a relationship for four years. After about 5-6 months, we broke up. I was depressed for about a year and had anxiety attacks because of it. Fortunately, my friends were there to support me during that time. I can say now that I’ve come out of that phase, but I still feel anxious at times. Honestly, I’ve lost trust in women. I feel like every girl is looking for someone better when comparing to me. I have a female best friend of 5-6 years, and I share everything with her. At some point, I started falling for her, but then I make myself realize that it would ruin our friendship. And even if I were to approach her, and by some chance she said yes (though I don't think that would happen), I would know that I’d start losing her, just like I lost my previous girlfriend. I need suggestions on how to proceed in my life since I’ve lost trust in girls. Also, I feel like I’m still not ready for a relationship, as I become so attached to people that when they leave, it impacts my mental health badly. Please help!
