Cognitive Behavioral Therapy, basically realizing you're having depressive thoughts and working on coming up with alternative ones instead.

It's mentally draining to be constantly fighting my brain like this. Nearly every moment of the day is my brain coming up with thoughts of uselessness, worthlessness, hopelessness. I've got ADHD so it's already a struggle focusing on things, but even more so when my brain tells me no one will ever love me and I have to stop and come up with examples to discredit that.

Has anyone been practicing CBT for a while? Do those thoughts just get easier to manage at some point? I am not seeing a light at the end of the tunnel (maybe not good to think of it that way), and thinking about having to do this for the rest of my life is wearing me down as well.
