29 years old bullied as an adult

i am 29 and an adult who has been bullied. the woman who bullied me has ostracised me from every person i have ever met. it’s still ongoing now, when i have no contact with her since 2023. she decided from the moment she met me through our mutual friend that she was going to destroy me and destroy any friendship i had formed with anyone who knew her but also knew me, and she managed to do it. she has isolated me from basically everyone. there is not one person i have managed to continue a friendship with because of the way she has bullied me. i have felt suicidal because of what she has done to me. i have nobody who is on my side or understands apart from my partner, who it is difficult for because a lot of his friends will not associate with me either because of her. she was extremely manipulative and clever causing me to retaliate at her in message, which she used to her advantage against me making it look one sided when she has made my life a misery from the moment she met me through a mutual friend. she wanted me out of the picture and she did her darnest to do it. it’s been three years and ongoing and i am SO alone. she has taken every person i’ve ever met away from me. i have no friends, not even one. she’s recently added one of my partners close friends and befriended her now after she saw her commenting on my
photos, and now they have become close friends when i even confided in my partners friend what she had done to me. it’s pathetic but i just can’t cope any longer i am so broken and exhausted.

thanks for anyone who listened
