Girl, I have been in the same situation for years. I have just graduated and wore my hijab for the entire time, even though I felt nothing towards it and only started wearing it because my mother became more religious after my grandfather passed away.
I was not forced into it, but I'm not sure about you. I think it's more appropriate to say I was "coerced" into it via guilt and peer-pressure. The guilt was towards my grandfather for not trying to be closer to him while he was still around, so I saw the hijab as a way of honouring his memory and showing solidarity with my mother, who had just started wearing it. (I was 12, so I think a part of it was simply because I wanted to mimic my mother.) Also, I had a bit of a trauma of my own body during puberty as it was changing, and I was sexually assaulted abroad during this time, so I think that played a role in me wanting to cover up, too, even though I was 12 when it happened. I did not tell anyone about it, and my mum said something about how women who don't cover up bring it upon themselves, so I did not feel comfortable talking about my assault with her, especially after the fact, as it was in a crowded market area and I did not know the face of the person who put his hands on me, so what would be the point? So yeah, a few unfortunate events(grandfather and great-grandmother died, assault, struggles with body changes, being told women who dress how they like bring it upon themselves etc) happened when I was 12, which led to me wearing it.
I feel like a hypocrite with it on, and I don't feel comfortable talking to other muslim women about it because I've had bad experiences with friends judging me, or they felt uncomfortable offering any advice. Also, It doesn't help that I knew two ppl at my uni(although we weren't friends) who didn't wear the hijab who seemed much more grounded and comfortable with their faith.
I was actually staying in on-campus accommodation in my 2nd year, but I felt awkward taking it off when most ppl knew me as a hijabi in my first year.
I have to say -
1. Be careful and take your time figuring out what to say to your parents - roleplay it in your head. If you have a more friendly relative, talk to them about it in confidence - maybe they can help break it to your parents for you or they can give you more advice. ONLY your parents deserve to be let down slowly. Don't feel obligated to get friends involved in the drama - they might just add to your troubles.
2. Decide to keep it on or take it off at the start of your degree because it's a new environment and a fresh start. If you don't commit now, it will only get more difficult. You will probably only feel this ready at the start of another new journey, which may be years after - e.g, at the start of your master's at another university, post-uni at the start of a new job or at the start of moving out into your own flat/house.
3.Also, when it comes to marriage, you don't want to portray yourself as something you are not. Some families have preferences for hijabi's/niqabi's etc. Chances are, your family will start talking seriously about marriage in your final year of uni, so make the change now so you don't have to have awkward conversations later. It might cause trouble in a future marriage if you decide 2 years into the marriage that you want to take it off, but your husband or his family are opposed to it and are worried about what their relatives and friends might think of your choice. Also, when it comes to kids, you need to set the bar. If you want your daughter to have a genuine choice without coercion, you need to make the change yourself first. (I took a stand against cousin marriage in my family, and ever since then, my grandmother has not troubled my younger cousins with the idea.)
Essentially, be the change you want to see in your family. If you are not ready yet, like me, that is fine too - just be aware that the longer you hide yourself, the longer you feel uncomfortable agreeing to a marriage based on what they think you are.
