Recently widowed dad of one

I’m 33 and was with my wife nearly 17 years. Now I think I’m realising that I will probably be alone for a very long time. I have no experience in meeting people, I never had to use dating apps or websites. There’s no way I could enter a relationship in this state, but we all have physical needs, we all want hugs and kisses and all that good stuff.
I’ve always loved being a dad but now there’s new jobs I didn’t have before. Hairdresser, insect-remover, Calendar-organiser. Meanwhile my actual job is basically on hold, less hours to fit around school. Our lifestyle will likely have to downgrade somewhat.

I’ve always been dad but do I have the emotional depth to be mum and dad? Can I replace what she used to provide?
