Why do I feel so alone even though I have people doing their best to be supportive?

Probably because your feeling of loneliness isn't actually based on if you are acompanied or not, it's based from some kind of psychological issue. I suggest you trust the people that are trying to help you, that way there are more chances that you'll get better :)

Loneliness is a strange emotion. Sometimes, even if we have lots of surrounding support, we still feel this emotion. It can be a symptom of depression. If it's serious, it's best to seek professional help.

It could be many things. It could be a mental disorder like depression, or it could be that although they support you, you’re not super close to them, or it could be something like what I experience. I’m introverted and I’m pretty inside my own head, I’m my own best friend and it’s difficult to really get close to people. But whatever it is I get the loneliness and I’m really sorry you have to go through it.

You can’t depend on others to make you feel good or happy or like you have a purpose. You have to learn how to love yourself because if you don’t then you will never be truly happy. I used to believe that I was ugly because I got that a lot and even though I had others supporting me and trying to make me happy I never really felt happy. Then when I got older I realized how lucky I was to look like do. Not many have my height and hair color. I started to feel better about myself even though I was told otherwise

Sometimes we feel alone because even though we have people who surround us and are supportive, it's not what we need in the moment. Often, people offer support in ways that they know how, rather than in a way that the person they are offering support to needs. When you feel alone, take a moment to ask yourself why that might be and if you're comfortable with it, talk to someone who is offering you their support about how they can best make you feel supportive. It might be difficult to do at first, but explaining that you're grateful for their support, but that you feel there are ways that might help you better. Generally speaking people will be receptive to ways that will help you.

Sometimes things are not easy. It doesn't seem to matter how many people we have supporting us, loving us, and being there for us. And that is okay. That is because you do go through life alone. No matter how your people are there for you, there are things you have to do for yourself and go through alone. Only you live your life and only you can heal yourself-- sometimes with the help of others, yes, but you can not heal without trying. Often it can feel lonely when you have supporters but are going through harder times alone because no one knows it. Know how much you can handle on your own and then use your supporters to give you the strength when you can't handle it on your own.
