Hi. I hope the above responses have helped guide you. But when I read your story I repeated this “he’s scared of meeting someone else and dating them and by that hurting me. (He’s a good guy, really really good guy)” read it again to yourself! He is not for you if he is not into you enough to only be with you.

I sensed you have a lot of thoughts racing in your mind and I feel your your situation but from a logical stance we have. Physical accident that us not life threatening, a break up you acted upon, a perusing of a relationship and your Wellbeing affected emotionally.

Life has it’s ups and down and I think there are much worse off scenarios. No one got killed in that accident! I hope you find the support to work on your self esteem and you time before getting into a serious relationship. I myself have had a bad time also but that’s life and it has helped to realise that I can’t blame the world but to work on myself within thus world. I have forgiven those who hurt me and realised me too also makes mistakes.
Counselling will help to talk your your feelings and gain perspective. Well done for speaking up and looking for help, best wishes.
