I believe The people closest to us (usually) don't want / mean to intentionally cause us disharmony or hurt. That being said, we all grew up playing “roles” in our family of origin codependent dynamics. Moms. Dads, siblings, husbands, friends, colleagues, bosses know exactly what to say / what to do to be manipulative and controlling (knowing / unknowingly) to get what they want.
As an adult now, you have the right to choose to say yes or no and ask for their understanding and respect of your decisions. Especially, a healthy decision to study to meet a goal that will enhance your future. I'm sure your mom / dad simply miss your smiling face and companionship, but this is a great opportunity for them (others) to find other hobbies, friends, alone time that doesn't interfere with your boundaries and need for space while studying.
To avoid hurting anyone's feelings or having an uncomfortable situation (which, yes, causes undue strain on you), the advice of a set study schedule sounds best. If mom, dad, siblings, spouse refuse to respect your study schedule and the time you do / can make for them, then the second best advice sounds like finding a library, coffee house, friend / boyfriends place to study at…… Turn phone on silent / off at this time at allow yourself , I'll say it again, allow yourself the time and energy you deserve to focus and complete your goal without giving others the opportunity to make you feel guilt or stress. I agree, don't lie, just be honest with the intention of love and kindness behind every word in trying to explain your time is of the essence right now – and that its temporary. Ask yourself the “10 rule”…… Will this be an issue in 10 days from now, 10 months from now or 10 years from now???? And to be completely transparent, I'm really talking to myself right now and not preaching to the choir bc I'm facing similar situation. If you find the answer, please share before you make millions off the it!!!! :-).
