Neglected

So lately me and my bf have been arguing. I asked him on video call if I still turn him on cause he hasn’t been doing it with me much like he use to. He said I do but he’s getting older and not feeling like doing it, like he use to. I have sexual needs but he’s the only guy that turns me on. I’ve been crying this week because I feel neglected by him. He told me to grow up and get help because he thinks I’m crazy. He doesn’t wanna talk to me for a while and told me it’s best if we are just friends. He suffers from drug addiction and I can understand why he’s being aggressive towards me. But how do I stop thinking about him too much? I’ve tried to distract myself but it doesn’t work. What should I do? Do I need professional help?
