To be honest, I feel empty most of evenings. Even when I come home from ice hockey match, it is something that ended, but what after that? Again, I am alone, no one to call/talk to, no one to share myself with. Even if something positive happens (only very small things and not often), it doesn't feel good if you have no one to share it with. Not to boast, but to share yourself.
I actually reach out to people I know (but there is not a friendship), but get no response. You know, I try to chat with people from my faculty (I don't know them at all), but chatting online is not fulfilling because of the system which is used. I also tried to invite people to meet several times (there are some threads for this), but no one responds to me, so I meet only a few people who I try to strike up a conversation with in real life, but they just don't want to socialize at all. I don't feel anxiety or other things stopping me from trying, it is that I can't find any poeple who would go out.
You know, listening to music (mostly rock/metal, but sometimes also blues) is an inevitable part of my life so it's not kind of hobby. Also, I sometimes read articles about psychology, searching for something, but that is also not a hobby. I cannot focus on my studies much because I can't work on computer longer than 15 minutes in one go.

I also feel, or better said, I know that I have things to offer to people as a person/friend/partner, I have also been told this by others (still, they abandoned me...), so it feels even more frustrating. According to these things, I think I have all the rights to feel that the problem is not my personality, so I don't know what to change for things to get better.

Exactly. Well, I don't compare myself to others, but it doesn't feel good to know that every person who I know and wants to be in a relationship is in a fulfilling one. It is not the reason why I try to find a girlfriend, I have other reasons for that, but it is not pleasant to know.

Well, no matter if this is all you have to say. After all, you are the only person who replies to me, so still, it may be helpful in some way.

You are right, I have no problem with commitments, I have strong will, I am brave, confident, I can face challenges, I have positive mindset when I try something or interact with other people.
It just feels that this is not enough...
