i recently updated my mac book pro to Catalina - bad mistake. It now takes longer to start up runs a little slower than it did before the upgrade. How can I c=go back the operating system I had before upgrading to catalina?

Going back to a previous release before Catalina is going to be a major undertaking, unless you backed up your entire boot disk beforehand.
I have yet to upgrade my five Macs to Catalina. One won't (it's an older computer, and High Sierra - 10.13.6 - is its terminal OS release). What I have done is twofold:
1. I created a virtual machine using Parallels Desktop for Mac and used the Mojave (10.14.6). If I upgrade to Catalina and find I can't run a 32-bit program I depend on, I have a fall-back release that can.
2. I used Carbon Copy Cloner ($39.99, http://www.bombich.com) to create a bootable backup of my entire Mojave system. If I decide to revert back after upgrading, CCC makes it a snap (I've used it before on older versions for this purpose).
3. I ran the 10.15 beta on a Parallels virtual machine. This is what convinced me to delay upgrading.
None of this will help you after the fact, but I hope it may help others thinking of upgrading.
My guess is that you will need to back up all of your applications, documents, preferences, etc. and then download and do a fresh install of your earlier OS release. As has been suggested, you'll probably benefit from working with Apple to do so.

Do you have a bootable clone backup from before the update? If so the easiest way to revert is to restore from the bootable clone.
If you don’t have a bootable clone you can still revert. You will have to erase your hard drive. So it is a must to perform a full backup of your data and applications before hand.
The links below are two articles on how to revert:

If you use Time Machine it is not a problem
I am sorry but that is an incomplete statement.
Time Machine won’t let you revert to an earlier OS but it can be used to restore data and applications and settings.

I made the mistake of upgrading to Catalina assuming that Adobe would go to 64 bit and my Photoshop subscription would function. Dumb move on my part.
I went to the Apple store and a very patient Guru guy had me back up all my data, which took three hours, then they kept my computer overnight., which was under an extended warranty and they installed Mojave for me.
It turned out that I had a backup and could have done it myself had I had the knowledge, but I didn't realize it until after they helped me.
The information posted previously here will give the information on what one needs to do to go back to Mojave until things get stabilized.

You say “Adobe” did not work for you with macOS Catalina? Very odd.
I have been running LR classic and Photoshop, subscription versions, under macOS Catalina and they work fine. Lightroom (new one) had a problem for a while but Adobe fixed that in the latest update.

Maybe Adobe resolved the problem, my house is in the middle of a re-model and I don't have access to my 27 inch Mac for another week since it had to be put in storage. I'm using my laptop in the meantime. I will check with Adobe when I am up and running again.

Lack of updates could explain it. But why can’t you update your laptop? You don’t have PS and LR on your laptop?

I also am sorry but you are wrong! You can go back as long as you have Time Machine backups from before you installed Catalina. Command R held while your Mac boots gives you several options. Choose Disk Utility then erase your hard drive. Exiting Disk Utility goes back to the screen where you have the option of restoring from a Time Machine backup or installing a new copy of OSX from Apple - this is usually the version of OSX your Mac was shipped with. Anyway if you have kept using Time Machine you can normally choose to restore a version prior to Catalina. You may, after the restore, need to go back into Time Machine (the App) and restore any data you may have created/modified since installing Catalina. I haven't done this last bit myself so there may be problems I'm not aware of. I backup my photos separately as well as in Time Machine.

My Catalina upgrade turned my computer into a slow motion OS. Hopefully MAC folks will fix this soon
