Anxiety nd relationships

Hi I’ve suffered from anxiety since age 12 I’m now nearly 30 I’ve tried therapy and medications none have seems to work meds made me feel even worse! I’ve been with my partner for 3 years now and he’s been amazing always try’s to understand me alway there for me couldn’t ask for a better bf tbh but me being me or should I say me living with this mental illness makes me feel and think stupidness I never feel good enough I never feel loved I put stupid things in to my head and let me stress this he has never done anything wrong to make me feel this way this is how I no it’s my mental illness it makes me feel so bad on him was just wondering if there’s anyone out there who’s like me and how yours relationships are ❤️
