I would advise you not to give up. You're young and there is time to figure things out, so just take your time. Everything doesn't have to be crystal clear right now. If things feel overwhelming, reach out to people who can help lighten the load. As a student, you have resources available to you to help you nagivate these waters and many people, myself included, know how scary the waters can appear when you feel unsure. You are not doing this alone. Don't be afraid to ask for help or slow down and take a break when things feel heavy. Try to work at your own pace, not the pace you feel you should be working at compared to others around you. Hope this helps.
