Truly, how do we know? We're not there to see if you're really like this or if you're exaggerating because you're feeling down. We can only go by what you say in your post. For example, it might be that your family isn't actually upset with you at all. We don't know. You might not really know if in fact you are depressed, as depressed people very often think the worst when the worst isn't really happening. But let's say you really don't give as much as you receive in your relationships -- you use the word "can't" but you actually can. If you want to. If you don't want to, you are happy with yourself and just unhappy with others giving you grief about it. You can deal with that by just ignoring the negative chatter. If these people are still spending time with you and talking to you they aren't all that upset as you think, right? When folks are really upset with you they stop having anything to do with you. I also note that it's your family that's upset with you, not your close friends. That also says something, because families we're stuck with by birth but friends are with you by choice. Says more. But again, if those people criticizing you are right, you can change if you really want to. It's up to you. As for treatment options, medication isn't the only show in town. Therapy is an even better option if it works, because you might find an actual fix to the problem, which medication doesn't currently offer. Peace.
Oh goodness, I'm sorry. You know, my son has sensory integration disorder. This involves some different things and for some people it can be very subtle. He feels things but differently than what is considered typical. First of all, he has what is called 'low registration'. He doesn't pick up cues from others socially all the time and he also literally doesn't notice what is going on around him. So, people can walk by him and be looking right at him and say hi and he doesn't respond. Why? Not to ignore them but because he never registered their being there, looking at him or voice. He has to work to 'notice' others. He also tends to be self preserving. As his mom, I sometimes see it as selfish but in reality, he's trying to take care of himself as best he can. The world is cruel, look out for thyself.
My son also is very sensitive to noise. He LOVES movies but for years would hold his hands over his ears when we went. Now he wears a hoodie and puts it over his head. He has headphones that cancel out noise at home (as I have a very loud second son!).
He also fidgets. We get him hand fidgets which help. But the reality of fidgeting is that is often done to keep you alert subconsciously.
So, perhaps your nervous system is a little out of whack like my sons. What helps him most is physical activity. Life some weights, do some push ups and go for a march (hitting feet on ground) or run around the house. Swimming is really a great exercise. (deep pressure and heavy lifting all in one). I'm happy to tell you more about sensory integration disorder if you think it matches at all and to be honest, from what you've written, it does sound similar.
Sounds like Asperger's. Try study a book on Body Language. (I think Allan Pease has one. Looks like Barbara Pease also has one.) And try various books on Asperger's Syndrome.
(I of course can't diagnose you here, it's just the first idea that popped into my mind as a possibility. Asperger people tend to look at the mouth more since that is where the words come from, whereas others tend to watch the eyes more because they see a wealth of information in other people's eyes.)
Communication can break down if other people are looking for emotions rather than words, and aspie people rely on words and don't emote the emotions others are looking for.
For example, a person smiles and says they are very sad. An aspie will conclude they are sad, because they said they were. Other people may conclude she is happy, because she is smiling.
See the movie Mozart And The Whale for an example.
Studying body language helped me become more aware of my own body language, and how to interpret the body language of others.
Aspie people can be the most kind and caring people, even if they don't emote the emotions others are looking for, they still feel it inside.
Aspie people also are very prone to depression, due to feelings of isolation.
(Depression is a whole nother topic. Finding a med that works for a particular person can be a long task. Worth it though if one is suffering greatly.)
