"I hate not being able to control my temper."
From my understanding, hate is one of those verbs that is followed by a gerund OR an infinitive. In this situation, is "being" a gerund?
From EF.com https://www.ef.com/ca/english-resources/english-grammar/using-hate-love/ the verbs "to hate", "to like", and "to love" The verbs hate, love, like, & prefer are usually followed by a gerund when the meaning is general, and by the infinitive when they refer to a particular time or situation. You must always use the infinitive with the expressions would love to, would hate to, etc. These verbs can also be followed by a that-clause or by a noun.
