Why do I always feel like loser all the time?

Just look at your path. Focus your attention on you, get to know this person.... Appreciate her...get to know who she is as if you didn't know her .. what is it that she likes, what's her strengths, what's her vibe ? Everyone has something.
I'd recommend that you begin a journal. New Year is the best time for this.. By writing things you ignite something within and that brings more and more fire within... Practising some kind of rituals might help you with this too.
Practice setting intentions: with every full moon let something go. With every new moon, invite something in. 🤞

I go through that daily myself.

It can be difficult. I’m so sorry. I have absolutely been there. 🖤

Go to a bar and get drunk. That's my solution.

Depression.
