Pregnancy after loss

I had a missed miscarriage in March of this year. I found out I was pregnant again this month. I am terrified to be happy but at the same time it makes me feel like a terrible person for not being excited. I'm worried it's going to happen again. I've not had any early pregnancy symptoms except for being tired, which was the same when I was pregnant with my son in 2019. Any advice on how to cope and not compare this pregnancy with my last? Some days I have no trouble at all, then other days that I don't feel as bloated or as tired I instantly go to the worst thoughts.
