Imposter syndrome
Imposter syndrome is a normal thing to go through (even multiple times). But here is the thing reaching out to your fellow students / employer / workmates can make a huge difference to how you are feeling.
Just being able to put it out there and see how other people deal with it can help you through when times are feeling tough.
When learning something new there is a good chance it will be difficult but it will get easier over time and before you know it, you have all this new gained knowledge that you can take with you into your new career.
Use imposter syndrome to your advantage, listen to yourself, reach out to those that are close to you, speak to your rubber duck. Most importantly do not feel like you are the only person who has struggled because everyone goes through imposter syndrome at some point.
Do not be afraid to not know what you are doing, remember you do not know what you don't know until you come across it. So seek out new ways of doing things keep moving forward.
Someone wrote something in one of the slack chatrooms that resonates with me they said "You define who you are" so get out there and show the world what you are capable of.
