I've been coming across people talking about negative or obsessive thoughts a lot recently so I wanted to share some things I've learned personally dealing with both:
1. If you have obsessive thoughts like I do sometimes, count numbers out of order. For example, thinking or saying: 5, 32, 14, 78, 6, 24, etc. This takes so much more effort than counting in order like we usually do that our brains will use the energy it's using to think obsessively to be able to do this instead. My obsessive thoughts will go away after 30 seconds to a few minutes of doing this.
2. Any time I had a negative thought over the past year and been aware of it I mindfully replaced it with a positive one directly after. I think it's had an accumulative, lasting effect. There's a saying that goes, "The first thought that goes through your mind is what you have been conditioned to think. What you think next defines who you are."
3. I've nervously and subconsciously picked at my skin and nails my entire life, but in the past year any time I noticed myself doing that I would kind of do what I described above, and do something positive directly after (like filing my nails or applying cuticle oil). Over time I replaced obsessively picking at my skin and nails with obsessively taking care of them. This new habit causes me far less stress, requires less energy, and occurs less often. If you're going to have obsessive habits, it's not so bad having them work in your favor.
Changing my mindset to working towards progress not perfection is what has helped most of all.
I can't remember who took the last picture, please let me know if it was you!
