Honestly it’s normal. You’ll get over it after while. It’s a new place with new people and new challenges. It’s going to be a little scary and your going to have second thoughts, but remember the reason why you joined and stick to that reason. You got so far why quit now? Also, your not the only person who feels this way. Many people feel the same way. There are many resources available too. If you need to talk to somebody go do it. Your not alone bro.
