Intern/externships for credit work load

Hello. This semester I’m doing an internship at my school for 3 credits (150 hours total) and I’m wondering if anyone else has done that and if it’s manageable/ if it affected your grades. I’d have to take the 3 credits anyways to meet 15 credits this semester but I’m having an anxiety attack over it lol.

I’ve taken this internship before over summer but there were very friendly post law school/prebar people there that I was able to shadow and they helped me greatly. But this semester there’s none of those people there and it’ll be just me talking to OPC and clients.

Sorry if I rambled, i just have a weird anxious feeling about this semester I haven’t felt since 1L lol
