Health - emotion problems

[misha2dope]

about 2 days ago i took 3 hits of lsd. this is my 3rd time using this substance. all of my experiences were amazing and very positive.
this is the most hits i ever took. 3 and some marijuana. i smoke weed occasionally. on my acid trip i was extremely positive and kept telling myself how great everything turns out when you think positive and i felt so good about myself.. i knew i was able to achieve anything i want with this attitude and that i should always be like this. next day i feel kinda depressed and lost. i have a gf which i love with all my heart and she does too but shes been talking to an old friend of hers and i got pretty jealous and this affected me even more.. my thoughts now are all incomplete and i dont know whats wrong with me. its a horrible feeling because i stopped talking and feel lonely. can someone please tell me if this is going to stay like this or is it going to go away... hopefully i can get some answers here. thanks
