Should I just cancel?

So I haven't been out anywhere with my friends in 3 1/2 years. It was mostly due to covid, pregnancy and my sons illness. I'm dying to go outside and socialise with my friends. I have been purposely staying inside to try and prevent my son from getting covid etc (we do go on walks etc). However, my family still goes out as usual, which is expected. So now I just think me staying inside won't really make a difference.

I'm in my 30's and staying with my family until I have my feet on the ground. I rarely ever ask my family to help out, I'm with my kids 24/7.so anyway I decided to ask my mum if it was okay if she could look after the kids. She was fine with it about 2 days ago, then today I gave her more details. She asked loads of questions which honestly made me feel like I'm about 15. For example, where I'm going, who I'm going with and what we are doing.

I answered the questions because I prefer to be honest. Then she came downstairs and asked me who I'm going with again, I told her my friends name and she turned up her nose. My friend is a guy and I don't know if that was the reason why she did it. She walked away and I asked her why she did it and she didn't really answer me. She's never met him by the way.

Now I'm questioning if I should even go. I'm going at night when the kids will be asleep anyway, so I don't understand why it's a big deal. I wanted to go and let my hair down for once and I don't even feel like I can go. My mum is the only person who can care for my son due to his illness.

I feel guilty for having fun or attempting to. Like why so many questions? Should I just stay home?
