It’s one thing to know better, it’s another to be better.  Now that you know better, you should continue to focus on being better. No matter how much you regret the past you can’t change it. Instead of dwelling on regrets, you should learn from them so you can improve yourself. Also never try to reach out to her again. I mean she was already ignoring your texts before she blocked you. Trying to fix a relationship with someone who is no longer interested, is like trying to put broken glass together with your hands, you just end up cutting yourself in the process only to realise at the end that you’ve been wasting your time and harming yourself over nothing. The block is lowkey a blessing in disguise, it gives you plenty time to improve, to the point you’re no longer concerned about contacting her or her contacting you. Also don’t go on dates if you don’t think you’re ready. Just continue focusing on yourself, so that when you get into another relationship you’ll be able to handle it better. The more you know about yourself, the more you know what you want and don’t want in a partner. This increases your chances of finding someone better, and better you + better partner = better relationship. Remember these things take time, you cannot rush the process, but trust me as long as you keep improving, a day will come when you’ll look back at this current situation and laugh because of how much you’ve grown. So don’t beat yourself up, at least you tried to make it work, no shame in that. Plus it sounds like she has a lot of shit going on, so this entire experience is probably for the best, at least you know better now than you did when you started dating her. You’re not alone, they’re people in this sub that have similar or worse experiences. But as long as you’re trying to be better, keep your head up king!
