Does anybody have the urge to take care of something

[Necoblast]

I don't have children so I don't know if some people without kids get the same thing or if I'm the weird one. I was thinking of fostering kittens but there is no room in the house for kittens or cats so I can't do that. Is it bad that I want something to rely on me for survival? If I don't volunteer at an animal shelter for example, they would just choose another applicant (there are many applicants for the animal shelter) and then the animals would be cared for anyways. But if for example, I see a kitten in a dumpster or something, it would rely on me to rescue it from the dumpster because there is no guarantee that somebody else will see it and rescue it. If I volunteer in a position that can be immediately replaced by one of the many applicants waiting for a position to volunteer, then it feels like I am making no difference because somebody will do it anyways. (Of course it would be different if the local animal shelter was understaffed)
Is this why people become parents? Is this my “mother instinct” kicking in and trying to tell me to have a baby, or am I secretly some kind of psychopath for wanting some helpless animal or thing to rely on me for survival? I don't just want to take care of something, I want to give it a good life that it would not have otherwise. Is this a selfish thing to want? does anybody else relate? Is it wrong of me to feel this way?

What are you actually doing at the moment, @Necoblast? Are you still in education / training, working or looking for work?

Ok so to clarify I said “the urge” not “The plan”. Currently I can't drive and might not be able to ever drive and I live in the middle of nowhere where you need a car to get anywhere, including an animal shelter, which is not accepting new volunteers. I know that I do not have the capability to take care of any animal and it would not be fair for me to even try because I don't want them to suffer and they are probably better off without me. I want a reason to live and wake up every morning, and my own enjoyment is not enough of a reason. I have no reason to wake up if I'm not doing something to make the world a better place. Currently I am waiting for summer break to be over so that I can do another year of high school because I need a few more classes to graduate. I literally have some kind of brain damage that makes it so that I don't feel excitement for future pleasure and I don't care much about having fun, so I need something else to motivate me, which is helping others and following my religion. If somebody asks me if I want to do something fun, I say “I don't have a preference” because I am literally unable to anticipate pleasure.
Yes I do take medication for it including antidepressants which make me feel fine. I don't know why I even wrote this. I was simply wondering if that urge was a normal human urge or if I should talk to my doctor or my priest about it.

@Necoblast if your desire (or urge as you call it) is to make a difference to some other living being, that's a relatively normal thing. Everyone wants their life to have meaning. I don't know if what you have described as "some kind of brain damage" was caused by a trauma or a disease or it's a mental health issue you're being treated for, but "feeling excitement for future pleasure" is really not the same as wanting your life to make a positive difference to others. You are still studying and perhaps intend to either go on to further education or get a job. It's not clear from your posts what sort of living accommodation you have or whether you are living independently. But I do know that you don't need a doctor or a priest to tell you that there is more to life than having fun, which you have made into an either/or, surmising that since you aren't really interested in "having fun", then your only other options to feel motivated to get up in the mornings is to either help others or follow your religion. Unless you've learnt some ability that will be useful to others, there is more to "helping others" than just wanting to do so. You should be focused now on developing a skill that will be useful. Perhaps become a veterinary nurse or a gardener or a carer, anything. Rather than fixating now on what's not in your life, use this time (and you are just a young adult) so that you will be able to be useful to others in your future. I wish you all the best in your life.
