Feel Depress

so yeah I got a call saying I could go back to school and I think they said they would do things a lot more differently because of social distancing and stuff. I'm not sure if I want to go though. despite school sucking, the work actually distracts me from my bad thoughts most of the time. that's kind of why I think it'll be good. I also have trouble paying attention at home so going back will probably help me focus. I'm usually lazy but when I have nothing good to do, I can become sorta hardworking. my therapist also said that it might help me. you may be asking "this seems good for you, why aren't you going?". wellll the problem is that I haven't went outside for a month and I don't want to go outside especially since I'm in a really bad place rn. I'm not sure if school can even help me in this moment and time. should I at least try going? what if I screw up something? how do i get the courage and motivation to go outside

please give me advice i really need some help
