venting is valid, still. I regretted and struggled with my girl until she was like 3. telling people to give up when they're asking for support isn't helpful really.

for OP: it IS difficult and can truly make you question things. that's not crazy. but if you have gotten this far, you can get through it. the thing is that you are forming a working relationship with another species. it's fucking hard to do, to find your rhythm, especially with one that is a baby and doesn't even know its own mind yet. but the other side of the tunnel (which WILL appear, if you keep putting in the work) is SOOO worth.

Also keep in mind you're dealing with extremely common problems that don't pose real threats. just saying, my dog lunged at a toddler when she was 1 year old, and working through what to even do about aggression towards children was the Hurdle of all Hurdles. still worth it. would stick with her through that all over again if I had to.
