Is this a BPD thing or am I just a trash person?

I feel like I'm slowly becoming more and more agoraphobic. I didn't leave the house all weekend and I'm afraid to be around people and do the whole social thing. I really love this job and I don't want to blow it, but is there a way to explain honestly what's going on? I feel like if I'm honest my contract won't be renewed since they would view me as a liability. 

And the lying doesn't end with work. I lie to get out of plans. I lie to cover up my binge eating disorder. And I HATE it, but I feel trapped. 

So yeah, in terms of work I don't know if being honest is possible at this point... I guess all I can do is stop in the future? I feel so guilty too.
