HEy elsa, i may be able to help you out with the channel.
I myself have had strikes on my own account and they are easy enough to deal with,
there is a number of things you can do to stop this from happening, the main one being getting partnered to a good network
After that going through your videos to see if there is any unlicensed material in them is a good idea, and taking them down and re-uploading them with out that material if possible,
As for wether you should make a new channel or not is really up to yourself, but my suggestion is to download all of you videos of of youtube, and not to upload anything until you get your channel back in good standing, which is simpy a matter of waiting a few weeks till it auto restores to good standing.
Within that waiting period, keep recording, keep editing, keeping doing what you do except for uploading. But don’t stop channel side work competley, reply to comments, make hcannel art and above all else, try and network and build subs or even meet other youtubers who can help you out or collaborate with you, on your current, or your new channel, which ever you decide to go with in the end. If you have trouble networking i can probably give you a hand there too as it’s probably what i’m best at when it comes to youtubing.
I hope this has helped, and also what’s your channel link 🙂 i’d be interested in checking out your work 🙂
