Sharing Our Innermost Thoughts

I lost my mom in dec 2020 and I was completely broken and then after a long time I met a girl online, she had the same situation, we talked, we created memories and slowly I fell for her and recently I proposed her but she couldn’t process it and we took a day break and then I saw her text that she too wanted it but didn’t know her feelings about me, so we continued for another day in relationship and yesterday i e after 1 day of relationship, she broke up with me telling me she’s gonna hurt me in future.
I was already broke due to my mom’s death and now this happened and I don’t know how to get back, I’m not strong anymore, I’m having breathlessness every now and then, cold sweats… I need her back in my life because she is the only one I share my feelings with and I miss her badly…
