Here I am crying out for help

I am the person who asked why does he not want to put our relationship on social media. I know it seems silly but things like this has caused me to spiral. I understand it’s not his fault at all and my mental health isn’t the best. I am on medication and see a therapist once a week but therapy hasn’t been helping.

Dating makes me feel suicidal sometimes because I have a huge fear of abandonment and rejection, it triggers me horribly and makes me want to KMS. If I feel a slight change in my parnters response then I automatically think he is going to leave me 😞 I don’t know how to get out of this cycle since therapy does not seem to be workign.

I have been verbally , emotionally and sexually abused by my past partner so I have extremely low self esteem. I do not feel comfortable telling my current partner this as I think it would scare him off. My anxiety is really bad and I am crying right now.

Edit : I am thinking about writing him a letter explaining what is going on. I feel so stupid since my family just met him and likes him a lot
