Background: I'm 18(M) and 5'7". Around 7/10 in looks. Still a virgin, had only one girlfriend who cheated early on in the relationship and broke up. Never kissed any girl. I've been that classic beta nerd (more of a geek and not a nerd tbh) who usually scored the highest in all exams at school effortlessly. Not to brag, but I've never studied hard, I just have fairly good IQ (I'm Indian). I've also been used as a beta orbiter by another girl for about 2 years. I was bullied hard as a kid for around 3-4 years, which left me with alot of insecurities.

I'm not currently practising cold approach and pickup stuff, but I plan to do it in college (beginning in a few months)

I discovered redpill and game at 17 (almost 10 months ago) and I've read voraciously about both. I've read alot of pickup, blue pill, MGTOW, blackpill and other posts, too. I do see flaws and merits of this stuff, but lately my mind has been just a mess.
I'm finding it hard to deal with insecurities (being short, not being 9/10 or 10/10 in looks, etc.). Even though I get that my beliefs will change tremendously over time and all of this stuff will not matter a few years later, it's still hard to accept that I've got one life and there's no way I could be that 'chad' or 'greek god' who can attract women just by his presence. Also, being short puts me at a disadvantage.
I have this fear that I'd get cheated on again if I ever get into a relationship, just because there are so many good looking and taller guys around. I feel 'not worthy' of all the 10s and 9s.

Q1. Did anybody here feel the same way in their teenage/early redpill days? How did you cope with it?

Q2. How should I begin a better social life in college and fairly succeed at relationships?

Q3. How do I deal with insecurities and the fear of being 'cucked' in the future?
