窶堙や?堙懌?堙ァ窶堙遺?堋「 is usually written in hiragana.
The -te form can't be used to express the gerund "waiting at the bus stop". You need to use a nominalazer for that purpose.
窶堙や?堙懌?堙ァ窶堙遺?堋ュ窶堙??敕ヲ窶堙ェ窶堙ゥ means more likely "is tiring because it' boring" since the -te form can express the cause/reason. If you want to say just "is boring and at the same time tiring", 窶堙や?堙懌?堙ァ窶堙遺?堋「窶堋オ窶敕ヲ窶堙ェ窶堙ゥ is more appropriate.
The rest is OK.
