Stick it out for that first year, honey. I say this as a 74-year-old grandmother experienced with college (St. Louis University about 40 years ago---double major), a young daughter (now deceased) who was a year ahead in school and got some college (photography major) before she died a wrongful death on Cape Cod in 2002, and the maternal grandmother/adoptive mom of my first-born granddaughter now completing her third Associates Degree at Jefferson College, a two-year community college in Missouri, starting off with Engineering (trig gave her problems, so she dropped it before it ruined her GPA and took a foundational Associates Degree), then Electronics in a program the Obama administration offered, and last but not least, Integrated Computer Manufacturing Design where she gets to program math formulas into a CNC machine and make stuff---she loves that!
Check to see if your technical college in Myrtle Beach has transferrable credits to a four-year college where you'd have access to a lot more course choices. Ask your tech school's counselor about this, and ask that the counselor works with you to build up the credits and courses you need to lead you into field you want. Check the course book of the college for what is available in the fashion industry, but don't be discouraged if there are slim pickings at the freshman level. Most colleges, junior or four-year, require the basics you are currently doing, and it tends to be less expensive at a tech or two-year college. Get these basics out of the way so you can get to the good stuff.
If you haven't done this already, look into the PELL GRANT---doubled in dollar amount by education-friendly Barack Obama to $7,900 a year, divided up by semesters. If you are dependent upon your parents, their income would be taken into account to see how much coverage you'd qualify to receive for your education, but my granddaughter was able to live on campus for $385 a month (included all utilities and Wi-Fi) and just walk to her classes. She liked the independence.
Check out any four-year colleges in your state (or other states you like) as a plan for the future once you get your freshman year under your belt. If your tech college does have transferrable credits, see if there is also a program where you could take a course in your field of interest off-campus (at another college) and still get credit towards your degree at the current college. This is something you would talk over with a college advisor, so don't be shy about making an appointment to discuss your goals and plans for the future. That's the college counselor's job.
If your dad or your mom is a military veteran, you would qualify for VA Education Benefits to the age of 26, as did my granddaughter due to me being a disabled military veteran from the Vietnam era. She got full-time VA dollars of $1,058 per month for full-time attendance, and this was in addition to the $3,500 per semester she received from the Pell Grant. If no military parents, look into possible scholarships. Keep your grades up above a B average, preferably even higher---aim for being listed on the prestigious DEAN'S LIST (something to discuss with your campus advisor), because this opens all sorts of doors for funding, four-year college admittance, and job opportunities once you get past the preliminary first year.
Use your campus library since it's free to students---look for how-to books on pattern making, or whatever else interests you in the realm of fashion design. Learn as much as you can on your own, but stick with the freshman coursework---it will pay off big in the end.
