What can i say, you’re super sensitive and you need to take care of yourself!
You need first of all to ground yourself. Secondly, do a protective bubble daily when you wake up to filter a bit the energies around you and to keep them away from attaching to you. Thirdly you’ve got to do a bit of clearing in regards the people you talk/ hang out with because it sounds like they’re sucking your energy. You must be having some people that have a lot of drama or negative energy which makes you drained when you communicate with them.
You don’t really send energy mentally, so you’re not giving it away in that sense. You get overwhelmed because you put yourself in the persons story/drama/ energies, you’re living it with them which makes you drained. Most people can’t see your energies, but subconsciously they do feel/ know them, which is why certain people might cling/ come to you in their darkest times because they “know” you will “heal”, help them release some of these energies. For example my mother doesnt even realise, but every time she’s filled with different energies and needs healing, she comes to me and holds my hand - i know what she’s doing because my palms are always filled with healing energy, so she comes to get healing from me… and after a bit she feels much lighter.
People take your energy too much because you allow them to. In order to change this you’ve got to take care of yourself in all ways. Remove toxic things from your life, reconsider your friends/ relationships, what music you listen to - yes, this is quite important. I used to listen to a lot of metal and hardcore music as a teenager, but since my awakening i can listen to this music only on certain days or in certain circumstances. If i try to listen to it right now i won’t be able to, i’d feel it too heavy and id feel very uncomfortable. I had actually quite a few times when i had to ask the people i was with to change the music because it was making me feel uncomfortable, anxious etc.
Be careful if you engage in a lot of gossip as that is negative talk and it may drain you too. Try to set up little daily rituals for yourself for cleansing your energy, do salt baths, aromatherapy or have flowers in your room. Do cleansing meditations, eat light food. Your body and energetic system is changing which is why you’re so sensitive now, so you should be careful with what’s surrounding you!
