I've been going on dates, though I've been unsuccessful at getting into a long term situation. I can get sex if I'm desperate enough for it. And I've been rejected plenty of times.
The issue is more that I'm not really clicking with people... I feel like nobody understands and accepts me.
Anyway, I slept it off... I just get into that headspace sometimes late at night when all I have are my restless thoughts.
People work differently. It just maybe , at the moment dating isn't for you and a relationship may come out of the blue with someone you work with , or in social circles. It could be that you are putting too much pressure on yourself. As they say, often relationships come out of the blue.
But take the pressure of yourself, focus on yourself academically or in other ways - a hobby or exercise and perhaps something will come out that confidence you exert in those fields.
Perhaps you need an emotion connection to click with someone now. I probably mostly identify with being demi sexual, in that, in general, it is only months or even a year down the line that i will suddenly really like someone sexually or emotionally and i start to become close to someone. I think i need that emotional connection before i become properly attracted to someone. I guess it is like dating in slow motion. It is rare that you meet someone you click with, the problem with tinder it that it just focuses on physical aspects. Which i am learning really probably don't matter too me. For example the last two girls i have been sexually attracted to have come from not pursuing them, although there was an initial physical attraction, i wasn't actively looking for a relationship or sex with them. We naturally just grew close over time. Relationships are built upon on something you need, and she needs (or he), proper personal qualities, not just looks. There is a subtle change in what you look for as you get older. Sure when you are young, physical looks dominate most people thoughts or actions, but i think that changes as you get older. Also, Tinder, Facebook, the internet, tv shows, the dating scene in general etc, is that it fools you into thinking you should like everyone or you need to get with someone. There is a lot of pressure on failure. You shouldn't feel like that. Think when you were back at school, you may have fancied one or two girls at most a year? The same applies when you are adult, it is just the pressures skew things. So when you date people you have to remember that you only been fishing in a very small section of a very big sea.
Good luck though.
