wa alaikum assalaam,
It is certainly wrongful actions by which your parents forbid what is halal and permissible unless their objective is to seek for you that which is
more suitable in terms of being halal and permissible.
In terms of what you should be doing, then consider consultation and support with trustworthy relatives and friends. This should be done after having attempted to demand your rights (respectfully but firmly and consistently) with regards to fair treatment and rights of (halal and permissible) marriage, studies and job.
With regards to being fearful of knowing how to love, then this is a non-issue as all love comes from Allah swt. He is the origin of love and by turning to Him further in faith and practice then that immense love will be discovered from within...
Allah’s Mercy comes before His Love. Thus, He shows mercy to all of creation by simply blessing each being with bounties such as existence, life, health, etc. His Love, which is a more particular form of His blessing, is reserved in the Qur’an for the more deserving of His servants, such as those who: believe, show excellence, repent, rely on Him, are just, fear Him and those who struggle against wrongdoing for His sake.
If Allah Most High did not love a servant first, they could never love Him. So if we want Allah to love us, we must show love to Him by doing the things He loves and leaving that which He doesn’t love, and we should know that the fact that we were given the ability to love Him, means He loved us in pre-eternity out of His pure largesse and generosity.
Understanding Allah's attributes Love and Mercy
Perform Salaatul Tahajjud regularly it is ideally recommended for these circumstances with seeking to develop inner strength and attaining the needs one aspires.
In the meantime, having spare time then seeking knowledge, improving practice and teaching/helping others has been honourably recommended.
