Hi, a long-time lurker here, but I've been feeling very similarly to you as well. Before lockdown, I went 4 years without self-harming and since I've been furloughed, I've had at least 2 meltdowns involving throwing my head against the wall repeatedly, bruising my head.
I'm not in a good place, I feel the same about the internet and watching people spew their racist opinions all over the place, family included.
My partner is drinking more and acting aggressively towards our new puppies - any attempts by me to encourage positive reinforcement and calmness is met with "I have owned dogs all my life, I know what I'm doing". One of our dogs peed with fear earlier today, he also grabbed the dog by the scruff of the neck and pushed him to the floor, yelping in front of a load of people and I feel implicated in the whole thing because I didn't do anything other than feel sick and teary.
Any attempts to talk to him about his drinking is "can we just not do this now!".
I feel trapped in a small flat with nobody to confide in, so I finally joined mumsnet.
This whole thing is horrible, but I'm glad we have a place to share feelings.
@Ihatecurtaintwitchers I hope you are OK x
