How do you deal with depression

I have decided to live on my own and I have my own house property but a family member asked me for a favor and I told her the truth I like to live alone and the peace that comes with it.

But they insisted and I said I don't think it is a good idea they bought themselves a ticket and arrived at home address with suitcases

I have anxiety around other people and because she is here I have closed myself off the my bedroom she's taking over my kitchen and I'm hungry in the mornings will wait for her to finish because when I'm cooking breakfast she goes straight to the kitchen gets in my way and I don't know how to politely say get out of the kitchen until I'm done.

Ever since she's been here I've been feeling depressed I haven't cleaned I haven't wanted to do anything I just feel overwhelmed with stress

She has a guest bedroom bathroom so she is comfortable and I'm polite she's found a job and ask me for rides it's becoming a burden because I have to drive her at a certain hour I have to drive back home and when I'm out in the morning like to take my time but I have to be back in time to take her to work pick her up I've asked her to walk the job is about a fifteen minute walk but she refuses.

I just feel like I can't live my life with her here I have a lot of things to get done and she's interrupted most of it

How do I let this go I'm just not sure how to live with someone else how to share the living spaces kitchen the days she's off I feel she is in the way when I'm going to cook, breakfast, lunch, dinner overall I've just been upset because I'm hungry and I don't have access to the kitchen because she's there

When I have things to do she assumes I'm not busy ask for rides around

What are tips to living happily with someone else not feeling like they are a chore or burden not feeling anger at them or frustration

I know it might be easy for some to have company over roommates but I'm not very social and I know some they don't mind when there's people in the kitchen around the area but I feel like they are interrupting me and they need to use the kitchen also so I should hurry and leave I feel rushed.

I just don't know what is going on with me I wish I was more social but I've been hurt in the past and it's left me closed off I don't trust people
