My senses change suddenly and I can't feel happy

[Senseschangehappiness]

Hello. I'm 17 and I really need help. I have sensory processing disorder. This never really bothered me when I was younger. In fact I rather enjoyed it. I  took pleasure in the feel of the carpets under my feet and the look of a candle seemed magical. Then when I was thirteen, I woke up one day and all my senses were different. Things tasted different, smelled different, sounded different. I could hear some sounds I couldn't hear before and I couldn't hear sounds I could before. Just like I had a constant feeling of happiness from my senses, I had a constant feeling of sadness. I got depressed. I didn't even realise it but my life was miserable. Then when I was 16 my spd went away and I felt okay but not magical. Then the senses changed again and I felt magical again and now they've changed back to the terrible state. I can't live like this. Nobody knows what's going on. Is there anyone out there with the same symptoms?
