does it get better? 😔

trigger warning: anxiety, OCD, depression, intrusive thinking

hi. we recently adopted a corgi that is 5 months old. she has been really good & taken to potty training & training in general. she likes her pen & relaxes in there but hated the crate at night. after 2 bad nights, i gave up & let her sleep in the bed with us & she only really had 1 accident the first night. none since. she is super jerky & a bit of a spaz because we have 2 cats. we started to shut the door at night to shut them out because she reacts immediately to their movement if they get in bed. she chases & herds them & we’ve been trying to work on her impulse control. I’ve taught her place, sit, stay, & leave it (with a treat being thrown on the ground). she still chases the cats at times but it was really overwhelming at first & I was truly eyes glued on her 25/8 at first. We’ve had her for 2 months now almost. I work from home as the sole caregiver which I should have thought about before because I suffer from severe anxiety & all of the above listed… This has brought it out of me like no other. when I picture my life ahead, I see a life of yelling at her to stop chasing the cats, chaos & me never getting sleep or relaxing. I have had more mental breakdowns & panic attacks than I can count worrying about this & how my life will look moving forward if this chaos continues. I’ve thought about rehoming her because I don’t think I can heal myself from these deep rooted issues with her around. she is good & smart & cute & I do love her but my mental health is really struggling to a point where I can barely get out of bed rn. I am going to be spending thousands in therapy bills to fix myself bc I don’t have great insurance. I’ve been in therapy for the whole 2 months & started as soon as we got her because I was so in the trenches. I cry uncontrollably when I’m left alone with her when my fiance leaves for work. my face is hollow. I feel ill. i’m starting to get chest pain. I gave up/am giving up all of my hobbies. I have been doing a good job taking care of her & meeting her needs & sacrificing but I just never see her listening to me or either of us with the cats. I don’t want to have to correct her every second of every day with the cats for the rest of her life. I dread it… I know I sound horrible & everyone says she’s just a puppy but I’m so concerned she will never learn so I continuously hover & correct her. my fiance says to just let her be a puppy & Im trying but I have a history of control issues, anxiety & OCD so it’s much easier said than done. I truly don’t know what to do. i am sleep deprived, a basket case that doesn’t leave the house out of fear she won’t sleep when i get home, & a literal sad sack of shit rn 😔
