relationships

Just a little background info; since I don't know where to ask this.
I've already been diagnosed with depression & anxiety
I find that I get into relationships for the wrong reasons, to fill a void. then I find myself building a relationship with men, and the more affection they give me( I cannot show strong affection at all, I have to force myself to show affection) the more I almost feel, repulsed. I start to feel like I dig a hole for myself so I end up breaking up with them because I get bored and uninterested in my partners
I feel really bad because men get so attached to me and I feel like I like them but I can't feel any emotions of happiness when something nice is done for me. my now ex boyfriend sent me a bouquet of flowers and a stuffed animal to my house today and I felt nothing
everytime I think I like the person I'm dating I'm taken back because my mind tells me yeah you like them, but emotionally I feel nothing it's just empty I can't feel that I have strong feelings for that person.
