i need help.

okay i genuinely think i have some type of separation anxiety and i need someone to agree and help me out. my boyfriend and i ft every single night (past 18 months) but the past week he hasnt been able to. i barely sleep, i feel like puking and overall have the worst anxiety. we actually got to sleep together irl yesterday after 2 weeks without seeing him and at one point he got up to pee and just didnt come back. he went and layed in his room to sleep and i got instant anxiety and went in there to get him. whats wrong with me
