I really feel for you so much as you wonder about your purpose in life and the way forward.
I know it might feel hard to relate when I say I believe you're wonderful. For a start, you're wondering about your purpose, which not a lot of people do, when you think about it. Many just go through life, schooling or working, without asking the deeper questions. While some are focused on 'What phone will I buy?' or 'How can I look more beautiful/handsome?', you are wondering about so much more. 'Why am I here?' is often a question that goes with such wonder.
I've found that the people who ask that question are the people who I personally vibe best with. At times, we can be looking to the 'wrong' people or environment to give us a sense of purpose. We may never find our purpose under such conditions. Looking to the people or environment that raises us to higher levels of consciousness and energy is the way to go. Looking for the 'right' people becomes the true challenge.
Making sense of the words that come to mind is testing. To say 'I'm fat' is not true. If you were fat, you'd be a big pile of mush with no bones or muscle etc. To say 'I am carrying a lot of unhealthy fat', can lead us to identify our self as 'I am someone who will endeavor to carry only healthy fat in my body'. How we manage to get to that point does require management and a goal.
'No life' can be felt through a lack of excitement. What naturally excites you? If you can't think of anything, don't worry. Sometimes it takes a lot of trial and error to find what truly excites us. What naturally excites us is typically where we'll find the people we vibe best with. For example, if drawing or illustrating excites us, we can vibe high with a group of inspirational fellow illustrators. A lot of creativity and imagination in such a circle.
'I'm a loser' is an interesting phrase, one we rarely truly consider the meaning of. For example, in order to 'fit in', do I feel like I am losing my natural sense of self? In not seeking excitement, am I losing my natural excitable self? By people not leading me to wonder more, am I losing my natural wonderful self? Or, am I losing hope because I surrounded by people who don't know how to raise me effectively? Basically, if I'm a loser, I must be losing something.
If we're feeling like 'a waste of space', it's often because no one has led us to the understanding of how to fill it. This lack of guidance is a fault in others, not us.
Hope you return :)
