So there was once a much younger DVMD, who was very much like you.
Young DVMD was first hired into a veterinary clinic at 17 years old. I was hired on as a kennel assistant, so mostly cleaning, restocking and occasionally helping with restraining pets. 17 year old DVMD was very shy, very insecure, very unconfident and very, very quiet. I had been working as a kennel attendent for quite a few months when I was pulled into the Dr office for a meeting. The owning vet and the office manager were telling me they want to move me up into a veterinary assistant position at some point, but they can't do it given how shy and quiet I am. (I was bad, I would show up, do my job, minimally interact with anyone and go home). They further stated that they will have to let me go if I can't improve upon my ability to communicate and interact.
Now, it sounds awful to tell someone whose nature is to be very reserved and introverted that they need to be less of that, but veterinary medicine does require a lot of communication, you need to have some confidence (at least in outward appearance) and you need to be able to connect with and engage clients. So they weren't wrong in telling me this and thankfully, they gave me the opportunity to work on it.
And work on it I did. I wanted to be a veterinarian and I needed this job and experience to get me there. Besides work was almost my safe place as home was horrible at this time in my life. So I did start to come out of that shell I had built to protect myself. Started to let my personality shine through, started interacting more, talking more. Stopped just showing up, minimally engaging with others and started to really partake and join in conversation, etc. It wasn't easy by any means, it took some time. It isn't my nature to be outgoing, talk much, etc, so it definitely took time.
However working on that did pay off, I was moved up into a veterinary assistant position and then eventually progressed through undergrad and off to vet school and now I am a vet. I am still insecure at times. I still have problems with confidence. I am still an introvert. But I have learned how to at least while talking with clients to suppress that aspect of me and to engage, interact, connect with clients and sound confident and competent for them. It is exhausting because my nature is to be more introverted so I do need time away from human interaction to recooperate after work, but as long as I can get that, we are ok.
I don't think you need to give up, I think you need to find a clinic willing to give you that chance to work on the communcation and engagement with clients and coworkers. I find it quite sad that they didn't at all mention to you prior that it was an issue and provide you with some time or at least guidance to improve. If it hadn't improved then I totally get where they are coming from, but you can't improve anything if you didn't know it was a problem to begin with.
I will echo some of the other posts though, if your goal is to do lab animal medicine/research, you can do this without necessarily needing a DVM, so it might be worthwhile to look into those avenues as well. Especially since obtaining a DVM is so expensive.
I wish you the best.
ETA: OId DVMDream just realized she was 17 years old almost 17 years ago.
