First time home owner - stressing is it normal?

Closed in on a 440k new construction house on a 7.6 mortgage rate (I go through a religious lender so my loan options are limited) I am in Texas. mortgage is 2800. Property tax: 800 Insurance: 200 Gas and electricity: ~ 200 Waters: 100 Internet 100

I am single no kids. 15k student loan debt. No cc. No car at moment (wfh). Head of household with my parent. Salary: 115k yearly Saving / emergency fund: 200k. 401k: 100k Down payment 50k. Seller covered the closing and agent fee. I feel like it’s a bit tight ? I feel like I rushed into buying this home I was not thinking properly or long term. I use to rent and it was like 2500 for a tiny apartment. Did I overextend my self ? I am not sure what to do now. This is my first month in and I’m kinda stressing. I haven’t applied to homestead exemption yet. Hope that reduces taxes a bit. I am happy but stressed at the same time. The house is great I enjoy staying in it.
