Will I ever be able to move on from my ex?

Long story short, I met a girl, she became my first girlfriend, I fell madly in love with her, and 10 months into the relationship, she cheated on me and then jumped into a new relationship overnight. For the first week or two, I was plagued by devastating heartbreak and separation anxiety. It was the worst emotional pain I'd ever felt in my life. It's now been 10 months since we broke up, and while I'm definitely not the complete mess I was when it first happened, I'm still not over it. I still think about her every day. My mind flashes back to our relationship non-stop. I'm bitter and jaded towards women and relationships in general. I've went out on a few dates and slept with some girls that I'm not even proud of having slept with, but I've failed to make a real connection. My confidence and self-esteem have been completely destroyed, I look for character flaws in every girl I meet, and can't see myself trusting or opening up to a girl again. I'm very depressed, lonely, and miserable. I try to avoid mentioning this to anyone, people just get annoyed and think it's ridiculous that it's been almost a year and I'm still not over it. I really don't know what to do anymore.
