To wait or not to wait?

Ive been chatting to a guy online for almost four months now,texting and calling each other alot,and putting alot of time into getting to know each other.He says he thinks im amazeing and is always saying he wants us to get together..and he has really been there for me and viceversa-so we’re close (as close as you can be without meeting someone.
Recently he suggested meeting up for newyear eve,which i was really up for.then he went quiet for a few days,before telling me he couldnt meet me because he has anxiety attacks..almost a phobia of going out(although he socialises with his mates and people he knows).
At first i thought it was the “hes just not into you” thing,and i decided to call it a day,but he kept contacting me saying he felt awful and i mean so much to him,could i wait till hes over this? So im torn,because if he didnt like me he wouldnt of invested so much time surely?I really like this guy and id like to support him with this if its genuine(no reason not to trust him) Ive said i will wait,but its playing on my mind,i could be waiting forever…so what would you do?
