Social anxiety and depression

I have been cooped up in the house for a while now and it definitely did not help me with my social anxiety. I mean I can still interact with people but it’s more awkward and I get more panicked. I think I’ve been alone with no one but my family (which is ok but it’s not the same as getting out and about) that I started to get into a slump. I don’t get out of bed most days I don’t go outside and my room is a mess. I don’t feel sad per say I kinda just wanna hang by myself all the time. My mom is freaking out about it. She keeps telling me I need to get out and exercise so I’ll get endorphins and then my anxiety and depression will magically disappear. I don’t know how to make her understand that, that is not how it works I can’t just do a few jumping jacks and magically be free of my anxiety and depression. If that were the case I would become a fitness guru. Anyone else feeling like this??
