That’s why it’s best to start with down only. Focus on working on your chords and chord changes. You can learn basic strumming patterns pretty easily with a bit of practice.

Once you feel comfortable with the chords you are working with and changing them without long pauses to adjust your fingers you can work on your strumming.

Honestly for now I would just strum 1, 2, 3, 4, 1, 2, 3, 4 and then change chord and repeat and then change back and repeat and then add a couple more chords and do the same.
