Not sure what is pissing you off. If it’s like most people right now it would be best to cold turkey social media and news. I was getting incredibly depressed by it so I quit it and I just stick my head in like once every couple of weeks, like today.
Exercise. Getting out of the house. Get reconnected and grounded. Get back to living in the moment. Remember to be grateful everyday for something. I know it sounds stupid when everything is burning down but just do it and see the results.
Check out self help books at the library for your conditions. I know when I couldn’t afford therapy or went a long way to getting mentally well is life time journey for many if not most.
And cold turkey any kind of meds for mental disorders is a scary thing. You’re an adult, you made that choice. You can always talk to your doctor about alternatives but I imagine you’re going cold turkey for reasons. Just be kind to yourself while you’re going through this transition. Know that this isn’t how you or things will always be. Be patient with yourself and take it one day at a time. Things will get better. You won’t always be angry at things. Question why you’re getting angry at things and ask yourself things like should you change your expectations.
I bought a no name brand battery for my laptop once off of ebay. Had zero problems with it. The battery life was like 1 year instead of 2 or something but otherwise it performed the same. Just make sure you pick a reputable seller or something with a lot of positive ratings.
