i think about it a lot

A week or so today i was talking with my mom about how i feel like at times, i told her im 29 physically but mentally i feel 18 or so. just dont feel as mature or something as everyone else my age. My mom told me that years back my therapist told her that i will always be mentally 10 years or so behind everyone else my age. and that statement has stuck with me, and feel there is obviously some truth to the statement. my therapist for context watched me grow up, (i saw him for 18 years bi weekly) from the age of 7-8 to 26 years old. its a odd feeling knowing im still so far behind.
