I’m regretting adopting my cat

My cat is lovely and so cute but I’m seriously regretting adopting him because I feel constantly overstimulated and my allergies, which I never had before him, are awful. I’ve watched every Jackson Galaxy video at this point to try and provide my cat the best life, but he’s so anxious it’s negatively impacting our relationship.

I’ve bought him every thing he needs toy wise, enrichment wise, his basic needs are more than met. He gets loads of cuddles and we play at least 4-5 times a day until he’s panting. I thought that’d help with the clinginess but it doesn’t. My cat cannot be separated from me as he has the most anxiety. I have to eat in my bedroom or standing up because he’s constantly trying to get on my lap and the table. I can’t crochet, color, play video games or paint anymore because he constantly needs to be on my lap, or he’s biting my paintbrushes and trying to lay all over my art supplies. It’s gotten to the point where I can’t do any of my hobbies because he’s so disruptive. We spend all of my free time together because he’s so needy. Right now as I’m writing this he’s biting my phone case and crying because I’m not petting him. I’m so stressed and I want him to be able to calm down.

Please don’t tell me to get another cat for him, I don’t have the money, time or mental health to handle another cat, I’m already stressed enough.
