Ikr!!
If u want u can check this manga out the mc can't see ppls faces due to trauma https://www.mangago.me/read-manga/harenai_sekai_de_kimi_dake_mieru/
Mc has anxiety but not really, it's like anxiety https://www.mangago.me/read-manga/happy_together_paradise_scans/
And https://www.mangago.me/read-manga/death_delayed_for_a_short_time_because_of_the_will/ more than anxiety it's ptsd and depression and the ml unknowingly makes mcs days better :>

suggest me a bl where the mc has anxiety(specifically social), paranoia, abandonment issues, maybe even bpd and long term depression but still acts tough, never truly opened up to anyone and is the avoidant type but will cry himself to sleep after trying to act 'normal' all day. and would be better if the ml helps him live a little. i know im being way too specific but i REALLY need anything similar to this right now
