I think I’ve been having mild dissociation from anxiety, I’ve read up on some symptoms and have a lot of them

But recently I haven’t been able to “feel” any of my emotions right, or even have emotions a lot  of the time. It’s like when everyone else gets happy or sad or something I just sit there and like I don’t feel anything at all. OR whenever I do feel something, I can’t even tell what it is anymore. I can’t tell if I’m happy or sad, anxious and depressed or totally relaxed. I can’t even tell if I like my girlfriend anymore or if I’m even horny ever. Like she will say she wants to have sex and I sit there like “do I want to?” “Do I feel horny now?” “Do I EVER feel horny?” “What does that even feel like I forget”. I just forget what every emotion feels like, so I can’t identify the emotions when they happen 

Is this a symptom of dissociation? Anxiety? How can I help this?
