Need some help

So after 2 months of reading and speaking with multiple Muslims I have taken the executive decision to take shahada soon.

All of the guidelines are pretty easy to follow and not a problem.

The main issue I have identified is the actual praying part, like i don’t speak Arabic and im not good at remembering texts and with 5 i feel like I will do it improperly

Another issue I find is actually learning about Islam because I got invited to Islam introductory course at a mosque but I don’t like people generally and I would feel too out of place.

So is there anyway I can teach myself correctly without having to go to a mosque.

And to do shahada do you have to go to a mosque ?
