There is a difference between love and attachment. Love is when you give. And you are still 'alive' when the loved one is taken away from you. Attachment is when you just 'take' and you become totally consumed with grief and unable to function when the 'attachment' is taken away from you. Love is good, attachment is not. It's unhealthy. If you want to go through one of the worst pains in life and bitter disappointment, get attached to someone.
Simple love should not cause us to act like drug addicts.
Apart from love and attachments, there is something else we need to pay attention to: concern. What is our concern the entire day...the entire life. Read this:
Ibn al-Qayyim (may Allaah have mercy on him) said:
“When a person spends his entire day with no other concern but Allaah alone, Allaah, may He be glorified, will take care of all his needs and take care of all that is worrying him; He will empty his heart so that it will be filled only with love for Him, free his tongue so that it will speak only in remembrance of Him (dhikr) and cause all his faculties to work only in obedience to Him. But if a person spends his entire day with no other concern but this world, Allaah will make him bear its distress, anxiety and pain; He will leave him to sort himself out, and cause his heart to be distracted from the love of Allaah towards the love of some created being, cause his tongue to speak only in remembering people instead of remembering Allaah, and cause him to use his talents and energy in obeying and serving them. So he will strive hard, labouring like some work-animal, to serve something other than Allaah… Everyone who turns away from being a true slave of Allaah and obeying Him and loving Him will be burdened with servitude, love and obedience to some created being. Allaah says (interpretation of the meaning): ‘And whosoever turns away (blinds himself) from the remembrance of the Most Beneficent (Allaah), We appoint for him a shaytaan (devil) to be a qareen (intimate companion) to him.’ [al-Zukhruf 43:36].”
Al-Fawaa’id, p. 159
It was narrated that Anas (may Allaah be pleased with him) said: The Prophet (peace and blessings of Allaah be upon him) said: “Whoever is mainly concerned about the Hereafter, Allaah will make him feel independent of others and will make him focused and content, and his worldly affairs will fall into place. But whoever is mainly concerned with this world, Allaah will make him feel in constant need of others and will make him distracted and unfocused, and he will get nothing of this world except what is decreed for him.”
(Narrated by al-Tirmidhi, 2389; classed as saheeh by Shaykh al-Albaani in Saheeh al-Jaami’, 6510).
Bottom line:
Turn to Allah in repentance. Ask Allah, beseech Him, to make His Pleasure your only concern. Then try to change for the better.
Allaah says (interpretation of the meaning):
“Whoever works righteousness — whether male or female — while he (or she) is a true believer (of Islamic Monotheism) verily, to him We will give a good life (in this world with respect, contentment and lawful provision), and We shall pay them certainly a reward in proportion to the best of what they used to do (i.e. Paradise in the Hereafter)”
[al-Nahl 16:97]
