Why I'm considering a different major

I started questioning if I wanted to be an interpreter this year. I have been in my classes and struggled with them since I got here. I have noticed an early burn out in myself and I am not sure I can handle this major as it stands. Here are some reasons why:

1. I am an introvert and this program chews us up and spits us out.
2. I've been struggling with my mental health since the second semester of my first year when I was sexually harassed. Then I was in a toxic situation with a roommate the next semester that sent me in a downward spiral that I've been struggling to get out of since.
3. I only ever wanted communication. I never wanted anything more than that. Interpreting was other people's dream for me. I convinced myself it was my own.
4. I can still work with Deaf people, I just am not sure this major is right for me.
5. I can't afford college.

The ones that have affected me the most are numbers 1, 2, and 3. The last two are important, but not as important as the first three. The hardest part about this will be telling my dad. My dad is my hero, I respect him. But the problem is, he tends to take things too personally. So, I already told my mom. She supports me in whatever I do. I am writing a letter to my dad because that's easier for him to read through. Sometimes certain tones or looks makes him feel challenged even though that's not what my intent is. Letters are easier and less intimidating.

I know I'm about to be the biggest disappointment there is. But I guess my therapist can hear all about it while I'm still here. 

Anyone ever feel like they're being used?

I think everyone has that one friend in college. They always want rides, depend on you too heavily, are always asking to hang out. I never liked being that friend, at one point in my life I probably was. I felt like I was anyway, my friends always told me I wasn't a bother. (I think I only asked for rides a few times, I usually liked to try and figure it out on my own.)

Well, currently I have a friend like this. She is always wanting rides from me, companionship, or affirmation. I didn't realize, when getting into this friendship, that I'd end up being her only source of friendship. I've encouraged interaction beyond me, but she doesn't seem to understand that I really am not required to help her.

If I decide to refuse to give her a ride somewhere or make her take the bus, she becomes agitated. Thankfully I don't live with her. She has also been open with the fact that she gossips about me to her friends. She usually uses cuss words to describe my behavior, even though I RARELY refuse to help her. The only time she "accepts" it is if I'm sick.

I can't think of a graceful way to end this friendship. We are in 90% of the same classes. I am trying to find sections of classes I need that are separate from hers so I don't need to deal with her 24/7.

I do feel like I'm being used. I know if I told her she'd find a way to turn it back on me. So, I've decided to remain quiet. I've given rides to other friends before and they've always been nice about it. Even if I need to back out, I tell them hours beforehand so they can find another ride. I've even negotiated rides with other people just so they wouldn't be left without help.

This friend says things then, "I'm joking". I have a feeling I accidentally placed myself in the hands of a bully and I can't get myself out of it. It's a super weird position to be in.
