Help

Hello Everyone I'm Dave, I didn't know I had Autism until 2 years ago 45 years old now and struggled with noises, bangs etc always presumed they where personal, struggled socialising then over doing or clinging onto friends then that would fall apart, its cost me my fiance she left after 7 years, I didn't understand why I always felt lonely, or people saw me as strange. I'm at the stage where I am not living alone, no friends and struggling tbh, I'm scared no friend, no relationship will ever happen again, I fear getting close to anyone because they will see my autism or mental health and like everyone run. So I'm reaching out to others who are gently graced with this still no fully understood diagnosis to see how or if what I said connects.
