I’ve had a 2 year relationship with my sons dad (no longer together) and he was mentally and emotionally abusive, I’ve been cheated on and lied to every relationship I’ve been in and now I’m in an almost 10 month relationship with the most amazing guy I could ask for, but I have so much anxiety and I guess you could say anxiety attacks every so often that my heart starts pounding through my chest I get red in the face I’m hysterically crying because I fear that one day he’s gonna cheat or leave me etc and I trust him with all my heart this the first relationship I’ve been in since leaving my sons Dad over a year ago

Any advice on how to overcome this??
